Description

200520698 发明 Description of the invention [Technical field to which the invention belongs] The present invention relates to the treatment of at least one component of mainstream smoke with a metal oxide type oxidation catalyst capable of supplying and storing oxygen, and in detail, to reduce the mainstream smoke Concentration of at least one catalyst-specific composition. . [Prior art]

Various attempts have been made to reduce or eliminate the sidestream smoke emitted when cigarettes are burned. The applicant has also developed various systems that can control the sidestream of cigarettes. These results are detailed in the international applications WO 98/16 1 25, WO 99/53778, WO 02/024005, WO 03/023903 and WO 03/077687 'The disclosures are incorporated herein by reference. These published applications describe various combinations of metal oxide type oxidation catalysts and adjuvants that can store and supply oxygen to reduce the amount of sidestream smoke visible to the naked eye from a burning cigarette. In order to reduce the amount of sidestream smoke from cigarettes, specific combinations of these metal oxide-type oxidation catalysts and auxiliaries that can store and supply oxygen can be used on cigarette paper / wrapping paper and / or cigarette rods. Examples of such metal oxide type oxidation catalysts and auxiliary materials which can store and supply oxygen are lanthanide-based metal oxides, typically hafnium oxide. In addition, these metal oxide type oxidation catalysts that can store and supply oxygen can be used in combination with other porous metal oxides to improve the control of sidestream smoke. In addition, the effects of mainstream smoke are generally considered negligible. For example, it is disclosed in the international application WO 00/002 0005 that the treatment of paper does not cause a major change in mainstream smoke, which is confirmed by the results of Example 2 of 200520698. For example, a conventional cigarette paper can produce I 50 micrograms of aromatic hydrocarbons composed of phenol and hydroquinone, compared to II 9 micrograms of aromaticity produced by a prototype cigarette containing treated paper. Hydrocarbons. In terms of weight, there is not much difference between 150 micrograms and U9 micrograms. In addition, when looking at the other components listed in Table 2B, the difference is not obvious. In many cases, the difference can even be ignored. In fact, in some cases, the weight is even slightly increased. Therefore, it can be concluded that there is no significant difference in the mainstream smoke produced by the treated composition. It also makes similar measurements for nicotine, furan, hydrocarbons, and other hydrocarbons. The use of metal oxides in cigarette tobacco to oxidize toxic components in cigarette smoke, such as carbon monoxide, is described in U.S. Patent No. 4,397,321 'which uses soot and a transition metal to reduce the carbon monoxide content in mainstream smoke. Regarding the international applications WO 03/020058 and WO 03/020059, both cases were assigned to Philip Morris Products, Inc., the international application WO 03/02 005 8 describes a filling composition comprising tobacco and a non-granular additive Thing. The additive acts as an oxidant or catalyst to convert carbon monoxide to carbon dioxide. Some such non-granular additives are iron oxide, titanium dioxide or hafnium oxide. International application WO 03/020059 discloses a tobacco blend comprising tobacco and an inorganic additive particle that reduces the combustion temperature of the burning portion of the tobacco blend, thereby reducing the generation of high temperature reaction gases such as carbon dioxide. The inorganic particles may be a metal oxide such as titanium dioxide or aluminum oxide.

Philip Morris has continued research and development on this type of cigarettes, and since 200520698, it has been discovered that, as disclosed in the international application wo 2004/041 008, grass or filters containing nano particles can reduce the amount of specific toxic components in mainstream smoke . These toxic components are selected from the group consisting of aldehydes, carbon monoxide, benzene, diisobutane, isoprene, dioxane, acrolein, acrylonitrile, hydrogen cyanide, o-toluidine, benzoylamine, nitrogen oxide, benzene, N -Nitroso-n-Nicotine, phenol, catechol, tolium, benzopyrene and mixtures thereof. International application WO 2 004/04 100 8 claims two U.S. priorities, namely U.S. Patent Application Nos. 2 004/0 025 8 95 published on February 12, 2004 and July 2003. US Patent Application No. 2003/0131859 published on May 17. The applicant in its published international application WO 98/1 6 125 discloses that catalytic materials or particles can be used to transform malodorous gases (for example, the composition of ammonia and aldehydes). Suitable catalysts such as precious metals, rare-earth metals, and the like, and mixtures thereof, are known, in particular, for the oxidation of such malodorous gases. This can be a problem when using a very activated oxidation catalyst that can supply oxygen, such as tritium oxide ', for smoking or lighting a cigarette. It has been proposed that the combination of ytterbium oxide with other forms of oxides can reduce the combustion problem, as disclosed in the applicant's published international application No. WO 03 / 〇77587. Although: It is hoped that this will reduce the amount of sidestream smoke from incense, but reducing the toxic composition in mainstream smoke is desired, or selective, regardless of whether the sidestream smoke is improved or not, processing the mainstream smoke composition is Desire. [Content] Unexpectedly, and contrary to Applicant's International Application No. WO02 / 024005's disclosure 200520698, the treatment composition can also be used to treat mainstream smoke. Such treatments can reduce at least one composition (for example, Carbon monoxide), the composition from the phenanthrene group, the composition from the carbonyl group, and other components such as ammonia, aromatic amines, 1,3-butanediene, isoprene-dilute, acrylic acetonitrile, and benzene The quantity is necessary. The same effect can also be achieved by the composition and cigarette structure defined by the applicant's international applications wo 02/024006 and WO 03/077 697. This mainstream smoke treatment can also be performed to reduce sidestream smoke. Very unexpectedly, the use of the treatment composition on paper, with or without controlled sidestream smoke, was able to treat and reduce the toxic composition in mainstream smoke. To further increase the activity of the oxygen supply material in the treatment composition, precious metals and smoke treatment materials can be used to enhance this effect, especially when the treatment material is used on paper or packaging paper. One aspect of the present invention is a method capable of reducing at least one composition selected from the carbonyl group and at least one composition selected from the phenol group of mainstream smoke from a burning cigarette. The method includes using a treatment composition on a cigarette paper.

The paper / wrapping paper can be a layer of cigarette paper or a layer of cigarette paper. The cigarette paper / wrapping paper can be used as a single cigarette paper or wrapping On the cigarette paper of a conventional cigarette. [Embodiment] Although the treatment composition of the present invention has a good effect on reducing the mainstream smoke composition when used on cigarette paper / wrapping paper, when the treatment material is used in tobacco and / or a cigarette It can also produce an acceptable mainstream smoke treatment effect. This can be achieved by using a treatment composition comprising a metal oxide type oxidation catalyst capable of supplying and storing oxygen, an auxiliary, or Optionally, a precious metal. The term "mainstream" smoke refers to a gas mixture that passes down a tobacco rod and exits from the end of the ferry, that is, when the burr is emitted or when it is smoked. The amount of smoke drawn at the proximal end of the cigarette. The mainstream smoke includes smoke inhaled from the ignition area and reaching this end. The smoke inhaled from the mouth can be improved by making the cigarette paper or fragrance filter more ventilated. The term "sidestream" smoke refers to a mixture of gases emitted from the end of a burning cigarette between two puffs and not directly inhaled by the smoker. Sidestream smoke consists of compounds that are visible to the naked eye (ie, aerosol particles) and gases that are not visible to the naked eye. With this treatment composition, the composition of at least one mainstream smoke can be reduced. Some compositions are as follows: carbonyls such as aldehydes and ketones, carbon monoxide, 3 butadiene, isoprene-diene, acrolein, acrylonitrile, hydrogen cyanide, o-xylene 9 200520698 amine, 2-prepared Amine, Nitric Oxide, Benzene, N-Nitroso-Nicotine, Phenols such as Catechol, Benzoanthracene, Benzofluorene and mixtures thereof. More specifically, it is known to be used. The helium treatment composition can reduce at least one of formic acid, acetic acid, acetone, acetic acid, propionaldehyde, butenal, methyl ethyl ketone, butyraldehyde, hydroquinone, resorcinol, catechol, benzene, and o-amidine Phenol, m-cresol and p-cresol, 1,3 · butadiene, isoprene-diene, acetonitrile, o-toluidine, benzene and ammonia. These compositions form part of the popular Hoffman analysis found in the cigarette industry, which is a group of compounds in a recognized mainstream smoke composition. A complete Huffman analyte member is as follows: carbon monoxide; composition in the phenol group (for example, catechol, phenol, hydroquinone, resorcinol, o-cresol, m-cresol, and p-fluorene Fen), the composition of several groups (for example, Jiajun, Yijun, propane, propionaldehyde, propionaldehyde, butenal, butyraldehyde, methyl ethyl ketone); ammonia; aromatic amines 1_aminofan, 2 -Aminopyrene, 3-aminobiphenyl, cardioaminobiphenyl); aromatic amines (o-toluidine, o-methoxyaniline, aniline, m-toluidine); aza- (aza-arene) Eugenol (eugen〇1); hydrogen cyanide; metal κ nickel, cadmium, crushed, lead, chromium, and ishiishi; mercury, · dioxide 1; nitrosamine nitroso-n-nicotine, 4- (N- N-nitrosoanabine (N-nitrosoanatabine, N-convex ^) N-nitrosoanabasine; PAHs (benzopyrene, pyrene, pyrene Phenanthrene-combined 3-vinylpyridine '· 1,3-butadiene, isoprene-diene; acetonitrile; benzene; toluene; and styrene. Using this treatment composition can reduce at least one Wuffman Analyte The concentration of members. In particular, 'When the treatment composition is used in a cigarette paper of 20/20/2020 / pack paper or above, and the composition of at least one selected from 0' can be reduced by at least one selected from several Composition of Phenol Groups Based on Mainstream Smoke

However, the raw materials behind the 4-gasification carbon mechanism can also be applied to the treatment of other selected Huffman analyte members. Although the amount of the treatment composition in cigarette paper / wrapping paper is still subject to change at present, it is possible to design a cigarette that emits side smoke of varying degrees. By increasing the amount of the treatment composition, the concentration of sidestream smoke visible to the naked eye can be reduced to a negligible amount. Conversely, by reducing the amount of the treatment composition, the concentration of sidestream smoke visible to the naked eye can be increased to the normal range. . In the case of a low-volume treatment composition, the main stream smoke is treated but the side stream smoke is still very noticeable. By changing the amount of the treatment composition in the cigarette paper / wrapping paper of the cigarette, it is possible to design an auxiliary which will emit sidestream smoke, although the level of characteristics is still at the same time, while still allowing the treatment of mainstream smoke to reach the desired level. As disclosed in International Patent Application No. WO02 / 024005, the full text of which is incorporated herein by reference, may be a suitable, almost non-combustible, finely divided particulate material that does not affect the flavor and flavor of mainstream smoke. Taste 'and does not emit any unwanted sidestream smoke vapor. The physical properties of the particulate matter are very stable at the high temperature of the burning cigarette core. The adjuvant may have a low surface area, generally less than about 20 m2 / g, preferably between 1 m2 / g and 15 m2 / g, and most preferably between about 3 m2 / g and 10 m2 / g. Note that for low surface area materials, although their particles are also finely divided, they are usually not porous. However, as the surface area increased to 20 m2 / g ', the particles became porous. The auxiliary may also have a surface area of more than 20 m2 / g, and at this stage, the particulate material is usually porous. The average pore diameter of the porous auxiliary is less than 100 nanometers (1, ooA). In an embodiment, the average pore diameter is less than 20 nanometers (200 μm, but typically, the average pore diameter is Between 0% and 10 nanometers (5 100a). As for zeolite-based materials, the average pore diameter is between about 0.5_1 · 3 nanometers (5-13 Α). Therefore, the porosity is Adsorption sites can be provided in the auxiliary to retain some mainstream smoke components to convert them into small molecules before they are released. The average particle size of the auxiliary particles is below about 30 microns, preferably below About 20 microns, more preferably less than i microns and up to about 0 microns. Non-combustible substances can be various types of porous clays commonly used to make cigarettes, such as bentonite or conditioning clay with high surface area. It can also be Use non-combustible carbon materials, including ground porous carbon fibers and particles. Different metal oxides and carbonates can also be used, such as porous monocubic mineral-based materials, including hafnium oxide, titanium dioxide, magnesium oxide, aluminum oxide Hafnium oxide , Tin oxide, iron oxide, manganese oxide, calcium carbonate, zirconium carbonate, magnesium carbonate, and mixtures thereof, metal oxide fibers such as milled rhenium fibers and other abrasive porous ceramic fibers and mixtures thereof. As for rhenium oxide, it can As a kind of auxiliaries that can be carefully distinguished from a thorium oxide oxidation catalyst that can store and supply oxygen. Other auxiliary materials include high surface area materials such as activated carbon and zeolite. The auxiliary can also contain high surface area adsorbent materials, which are non-combustible Intricately distinguished inorganic particles, such as molecular sieves, which include zeolites and amorphous materials such as Shixi soil / lin earth and similar components. Typical auxiliary materials used are 12 200520698 such as siliceous zeolite, X, Y, and B, J3 zeolites, modern zeolites, ZSM zeolites and zeolites such as / m S are acceptable. In certain embodiments, the ideal zeolites include hydrophobic zeolites and slightly hydrophobic zeolites, which are hydrophobic and slightly hydrophobic. Organic components have affinity. The zeolite material provides a highly porous structure that can selectively adsorb and absorb components in cigarette smoke The highly porous structure generally includes a macroporous structure between particles, and a microporous structure in the particles, which is branched from the macroporous structure. The Buddhist stone material can also be described by the following chemical formula: MmM'nM, , P [aA102 .bSi02 .cT02] where “is a monovalent cation, M ′ is a divalent cation, and M” is a trivalent cation,

, Fu Shi = adsorption material. In particular, the use of -gradient, can be customized design 'to selectively adsorb, for example, high Buddha point material, middle Buddha point material and low boiling point material. It can form a layer of the jishi composition ... This is a metal oxide type oxidation catalyst that can be used to store and supply oxygen for use in these materials. These material layers are then bonded with a binding agent or absorbent to the scented end paper / packaging paper used to package the straw. The binding agent or leisure agent can be polyvinyl acetate, polyvinyl alcohol methylcellulose (C is called starch and casein or soy protein and its mixture. Metal oxide type oxidation catalysts that can supply and store oxygen can choose free transition metal oxides (such as IVB, vb,

VIII, IB is known as oxides of metals), rare earth metal oxides (such as rhenium, princess, and lanthanide series metals, that is, lanthanum) and mixtures thereof. It is known that catalysts can exist in the form of their metal oxides or metal oxide precursors, and these catalysts can be converted to catalytically active metal oxides at the temperature at which cigarettes are burned. For example, a hafnium catalyst precursor can exist in the form of a hafnium salt (such as 'hafnium nitrate') or other dispersed hafnium form that can be applied to a solution or solid solution to adsorb metals, and can be converted to a high temperature at the high temperature of cigarette burning Catalyst function of thorium oxide. In the present invention, the term catalyst includes a catalyst precursor. In a typical embodiment, the lanthanide-based metal oxide can supply and store oxygen. 14 200520698 The metal oxide-type oxidation catalyst of gas is an oxide of the following metals, including lanthanum, thorium, tungsten, tungsten, and mixtures thereof. 'And the transition metal oxide is an oxide of the following metals' includes iron, copper, silver, manganese, hunger, tungsten, and mixtures thereof. More typical are 'rhenium oxide, hafnium oxide, iron oxide or a mixture thereof. The metal oxide type oxidation catalyst capable of supplying and storing oxygen may be selected from the group consisting of transition metal oxides (such as ivb, vb,

VnB, VIII, metal oxides), rare earth metal oxides (such as sharp, yttrium and lanthanide metals, also #, lanthanum). Typical transition metal oxides used in mixtures are oxides of metals such as iron, copper, silver, manganese, titanium, zirconium, vanadium, and tungsten, and mixtures thereof. The metal oxide type oxidation catalyst which can supply and store oxygen can also be used with other catalysts. Such catalysts include precious metals and metals from groups HA, IVA, and mixtures thereof. Examples include tin, platinum, and mixtures thereof. A solid solution of a mixed metal oxide type oxidation catalyst capable of supplying and storing oxygen, and optionally including a precious metal, can be prepared and used in cigarettes. For example, the metal oxide-type oxidation catalyst that can supply and store oxygen can be hafnium oxide, which is used in combination with any transition metal (such as :). Some combinations of metal oxides can include brocade / Steel mixed oxide 1 / junction mixed oxide 'Hr / zr / lanthanum mixed oxide, brocade ^ = oxygen: please / rotten / wrong mixed oxide' decorated / saki mixed oxygen two and mixtures thereof. Combined use of precious metals Some examples include: plutonium / wrong, Japanese oxide / handle '钸 / wrong mixed oxide / fossil / handle, decorative / steel mixed oxide ^ / 15 200520698 handle, thorium / 钸 / lanthanum mixed oxide / palladium铺 钸 鍅 / 鍅 / 镨 mixed oxide / palladium, 钸 / 钸 / lanthanum / rhenium mixed oxide / saturated, 钸 / dream, and Japanese 'converge this δ oxide / saturated, decorated / lanthanum mixed oxide / Platinum, osmium / rhenium mixed oxide / meal lice compound / platinum, osmium / zirconium / lanthanum mixed oxide / platinum, osmium / zirconium / rhenium mixed oxide / 1 white, brocade / lead / lanthanum / rhenium mixed oxide Object / Beginning, Plutonium / Fault / Symbolic Mixed Oxide / Famous White, Plutonium / Lanadium Mixed Material // The Mixed Distinguishment of this Lice Compound / Germanium, Plutonium / Plutonium Mixed Oxide Record, Decorated / Fault / Lanadium Mixed Oxide / Money, 钸 / 错 / 镨 Mixed Oxide / 锦, Brocade / Steel / 镨 Mixed Oxide / 姥, 钸 / 错 / 敛 Mixed Oxide / Money and Its Things-Precious metals and the available and Oxygen-containing metal oxide-type oxidation catalysts are used in combination and incorporated into the individual composition of the cigarette " Temple, which can positively affect the release of the + emulsified metal-emulsion-type oxidation catalyst that can supply and store oxygen The temperature of oxygen. For example, the cover net compound cb JL ± rtn. Λ.Α, and U.S. U. US Patent Application No. 2003/0004060 revealed that the precious metal should be used in combination with the metal that supplies and stores oxygen. In the case of an oxide-type oxidation catalyst, the temperature at which the metal oxide-type oxidation catalyst that supplies and stores oxygen can release oxygen can be lowered. Therefore, a treatment composition containing rhenium, osmium, and palladium can be used. It is incorporated into a cigarette paper / wrapping paper buried in a fragrant goods, and releases oxygen at a temperature of about 200 ° C. The treatment composition with the same composition as described above, but without palladium, will be relatively high. The temperature (about 500 ° C) is not ready until the oxygen is released. As shown in Example 4. Such as oxidized catalyst, can be used together with auxiliary. In a typical embodiment, the catalyst system is almost adjacent to the auxiliary. The catalyst and the admixture of additives can be formulated in many ways, for example, as disclosed in International Patent Application WO 02/024005. It can be mixed from the spleen, pi, w, and succinctly. The metal oxide-type oxidation catalyst particles that can supply and store oxygen can be mixed with the auxiliary, and the auxiliary layer can be added to a catalyst. Covers this smoke flow control characteristic. The composition of the oxidation catalyst of the elimination type. For example, the metal oxide of oxygen simply uses 10% to 72% of the palladium or other related metal between the supplyable agent and the auxiliary and the oxygen storage agent. Oxidation catalyst and other special catalysts that can be used to modify cigarettes or used in cigarette manufacturing agents will not adversely affect the use of different oxygen-containing metal oxidizing materials for the purpose of blending into a salt solution (Such as the surface of a nitro material. It can be used by contacting, coating the auxiliary on the catalyst or making the porous surface of the auxiliary to achieve the ideal excellent side. In addition to the metal oxidation auxiliary that can supply and store oxygen, it can also be used. Many other additions, when porous hafnium oxide is used as the supply and storage type oxidation catalyst, and mixed with auxiliary materials, precious metals are mixed with it. And the amount of metal oxide type oxidation catalyst used to store oxygen is typically used in About 1% to 75% of the available oxide-type oxidation catalysts, more preferably about 1 and metal oxide-type oxidation catalysts that store oxygen 20 % To 7G% of the metal oxide that can supply and store oxygen, based on the total equivalent of the metal oxide auxiliary that can supply and store oxygen is 100%. Additives to further strengthen the treatment or collection of mainstream smoke. Such additional additives can be mixed with the treatment composition elsewhere, provided that, of course, this type of addition of the treatment composition is capable of treating mainstream smoke. Methods to formulate the composition to achieve the availability and storage-type oxidation Catalyst (e.g., thorium oxide) and absorption (for example, the absorbent material can be sprayed or dripped with a broth or broth solid solution) to incorporate thorium into the absorbent and prepare it-mixed with the absorbent material in Fine powder isolated together with 17 200520698. In one embodiment, the catalyst powder has an average particle size of less than about 30 microns, less than about 20 microns, and about 1 to 5 microns to ensure that the materials are sufficiently mixed or blended with each other. The catalytic activity can be improved by increasing the surface area of the catalyst particles. Therefore, it is preferable to use nano-grade catalyst particles', such as particles having an average particle size between about 5 nm and 500 nm, as disclosed in International Patent Application No. WO 2004/04 1 008. For the general selection of catalyst particle size and surface area, the catalyst

The chemical agent should have sufficient surface area to ensure that the catalyst's site of action can interact with the moving sidestream smoke component. While adhering to the selection criteria of the catalyst, it is also another option to use a smaller particle volume, that is, to use larger particles, for example, in some embodiments using a particle size greater than 30 microns, where the catalyst is Porous, with a surface area of more than 20m2 / g or even 100m2 / g. Large porous particles have the ability to absorb smoke composition, and their catalytic properties: converted into small molecules and released. These large particles are particularly useful for targeting tobacco or cigarette implements. It is mentioned that the particles must be evenly dispersed to achieve the desired degree of mainstream smoke oxidation.

--- ~ W; 疋 Shaohuan is enough to show the dual function of the oxide of the present invention, namely, as a metal oxide-type oxidation catalyst and auxiliary which can store oxygen in two ways. The particles can be made to the high surface particle size required for the adjuvant. The hafnium oxide is used as a catalyst for cigarette paper / grass and / or cigarette filters in the first amount, and as an auxiliary in the treatment composition in the second amount. According to the other total weight of the present invention, the amount of rhenium used is equivalent to the content used in the catalyst and auxiliary. The decoration can also be formulated as a solution dispersion, such as a holmium oxide solid solution or the like, and applied to an adsorbent material such as zeolite. Then, it is dried and baked, so that the hafnium oxide can be fixed on the surface of the adsorbent material. When the hafnium oxide particles are fixed on the surface of the auxiliary, such as the surface of zeolite, the average particle size can be less than 1 micron. The relative content of thorium oxide fixed on the surface of the zeolite may be between about 1% and 75 5 miles, based on the total equivalents of thorium oxide and zeolite content. The relative content of hafnium oxide fixed on the surface of the zeolite ranges from about 10% to 70% by weight, based on the total equivalents of hafnium oxide and zeolite content, which is ideal. The ideal method for preparing the hafnium oxide combination product fixed on the zeolite surface was described on September 13, 2002, and entitled "A Process For making metal oxide- Coated MiCroporous Materials) "has been published and is still pending in US Patent Application Serial No. 10 / 242,675, the entirety of which is incorporated herein by reference. Although the above-mentioned application document provides a step for manufacturing a catalyzed hafnium oxide-coated zeolite particulate material, it contains at least 1% by weight of hafnium oxide coated on the outer surface of the zeolite particulate material, based on the total equivalent of hafnium oxide and zeolite content Number as a benchmark. The method generally includes the following steps: (i) combining a certain amount of a hydrocolloid dispersion of rhenium oxide hydrate (rhenium hydroxide) with a compatible zeolite particulate material to form a slurry, the quantitative hydrocolloid dispersion system It is sufficient to provide more than 20% by weight of thorium oxide in the heat treatment in step (丨 丨). The zeolite particulate material has an average pore size of less than 20a 19 200520698. The hydrocolloid is divided into 1 and 9 s 9 And having a pore size of at least 20 A to place the hydrocolloid dispersion on the outer surface of the zeolite; and heat-treating the slurry at a temperature (ii) first at a temperature of less than about 200 ° g 'so as to provide a Free matter 'is followed by heating rhenium oxide at temperatures above about 400 ° C to fix large particles flowing on the outer surface of the zeolite particulate material. Another way of the above method is to immerse the auxiliary material of the adsorbent in a salt solution, and then perform drying and heat treatment to form the thorium oxide on the surface of the adsorbent material. With regard to precious metals, the amount of the precious metal in the treatment composition is usually up to about 5% of the total weight of the treatment composition, typically from about 0.05% to about 1%. The precious metal can be selected from the group consisting of palladium, platinum, yttrium, fine, gold and silver. The precious metals used are typically selected from the group consisting of palladium, platinum, and thallium and mixtures thereof. More typical systems use handles. The synergistic effect of precious metals on reducing the mainstream smoke composition can be confirmed by the combination of metal oxide type oxidation catalysts, auxiliary materials and precious metals that can supply and store oxygen. It is known that the cumulative effect of the metal oxide-type oxidation catalyst, auxiliary material and precious metal that can supply and store oxygen far exceeds the metal oxide-type oxidation catalyst and precious metal mixture that can supply and store oxygen plus b) — auxiliary Individuals and precious metal mixtures can reduce the total composition of mainstream smoke composition. This selective precious metal-containing treatment composition can be applied to cigarette paper / wrapping paper in a variety of ways to reduce the amount of mainstream smoke composition. The treatment composition can be used as a filter in the manufacturing process of cigarette paper / wrapping paper, embedded in the cigarette paper / wrapping paper, or as a coating on the outer or inner surface of the cigarette paper / wrapping paper. The cigarette paper / wrapping paper containing the treatment composition can be used as a layer of outer wrapping paper for a cigarette having a conventional cigarette paper. The cigarette paper / wrapping paper described herein can be used as the cigarette paper / wrapping paper of central tobacco in a single layer or multiple layers. Referring to a conventional cigarette, cigarette paper or cigarette paper / wrapping paper fiber wrapped in a commercially available cigarette, the porosity is typically between about 5 to about 50 grams of Cresta units, sometimes up to no to 120 A unit of gram, and its free burning rate is about 3 to 5 millimeters per minute for a conventional tobacco density of about 0.20 to about 0.26 grams per cubic centimeter. Traditional cigarettes, at least in North America, have a circumference of about 20 to 30 mm, usually about 23 to 27 mm; and a length of at least about 40 mm, preferably about 55 mm; about 64 mm to about 74 mm The length between millimeters is resistant to pumping. When a cigarette paper / wrapping paper containing the treatment composition is coated on and in close contact with the incense cigarette paper, this arrangement allows the use of traditional incense and, when smoked, is traditionally free-burning Rate burning. Other uses of the treatment composition include incorporating it into tobacco to reduce the amount of mainstream smoke composition. This incorporation step can be performed at any point before the tobacco product is finally packaged. For tobacco, the treatment composition can be performed before or after mixing the various herbicides, if there is such a mixing step. In addition, the treatment composition is uniformly dispersed in the treated tobacco and can be used in one or all of the blended tobaccos. Typically, the treatment composition is evenly divided 21 200520698 ′ which can be evenly dispersed in the treated tobacco so that the tobacco 祜 will be effective during smoking during breakfast lighting. The ratio is between about 1% to about 10% by weight of the treatment composition added to the tobacco, preferably in the following weight ratios (based on the weight of the above-mentioned composition used for the grass, to provide useful tobacco products. The amount can be between about 1% to about 15% (weight% / 0) (% by weight) based on the weight of the tobacco.

The final grass can be further processed and formed into any desired shape or made available to the user in a loose form. Without departing from the scope of the present invention, other conventional additives such as flavors or wetting agents may be added. Other uses of the treatment composition to reduce the mainstream smoke composition include incorporating the treatment composition into a filter. The treatment composition may be sealed in a chamber in a cigarette holder. A coaxial ferrule may be used, wherein the treatment composition is incorporated into the filter layer or is between different filter layers. An example of a coaxial filter is disclosed in Applicant's International Patent Application No. wo 98/16125. In the examples, the composition can be simply sprayed on one or both sides of the cigarette paper / wrapping paper and adsorbed by the cigarette paper. , And / or sprayed on the cigarette paper fiber and / or cigarette filter fiber. Alternatively, the composition may be extruded in the form of a film onto the surface of a tobacco rod, a filter, and / or a cigarette paper / wrapping paper, and may be one or more layers. The treatment composition can be applied to a conventional cigarette by applying it outside a conventional cigarette paper. The treatment composition may also be embedded in tobacco fibers, filter fibers, and / or cigarette paper / wrapping paper, for example, the treatment composition may be forcedly applied to the tobacco fibers, filter fibers, and / or cigarette paper / In the wrapping paper, the composition of the treatment composition was embedded and infiltrated by 22 200520698. Familiar with this artist library_Station i 丨 + It should be understood that other different & including transfer coating methods can be used to make dian + ming processing materials. In the transfer process, the coating composition can be applied using MylarTM multi-method plates or other suitable plates.

The Mylar tablet is transferred to the cigarette paper, and the material is from the cigarette, the surface. This type of transfer coating can be used when the physical strength of sheets of U-sheet 5 or similar is not suitable for roller coating groups. σ. Another alternative is to incorporate the treatment composition in grass, incense, and / or tobacco / wrapping paper. The composition can be incorporated into the pulp as a slurry. Another alternative is to sandwich the treatment composition between layers of paper to form a double-layer tobacco paper that is wrapped around a tobacco rod. For example, the composition can be described by spraying: Licheng: Kcheng & Heli is on the inside of the outer paper or on the outside of the inner paper. Once the two layers of paper are used in the cigarette kneading and blending into the early pestle, the composition can be sandwiched between the two layers of cigarette paper in the form of a thin layer. Each-* layer of cigarette secrets is made of x, ′, and has half the thickness of traditional cigarette paper, so double-layer rolled paper does not increase the overall diameter of the cigarette, and can be completed by a cigarette manufacturing machine. In addition, a coating layer may be added to the inner surface of the cigarette paper adjacent to the straw, and the coating layer includes the treatment composition. ° The unexpected activity of the treatment composition makes it useful for a wide range of pores

The treatment combination ranges from 1 to 5 grams of extremely low porosity cigarette paper / wrapping paper, to about 1,000 grams of extremely high porosity cigarette paper / package. In a special embodiment of the paper, the porosity may be lower than 200 grams of units or between, ', spoon 30 to 60 grams of units. Please note that the cigarette paper / wrapping paper can be used in single layer, double layer 23 200520698 or multiple layers. The cigarette paper / wrapping paper can be applied to a cigarette having a conventional cigarette paper as an outer wrapping layer. Depending on the porosity, some catalysts and adjuvant combinations work better than others. Those skilled in the art should be able to understand that the foregoing methods for providing a treatment composition in or on cigarette paper / wrapping paper, tobacco and or filters may be determined by the amount provided, cigarette paper / wrapping paper, and used on tobacco rods. The number of wrapping paper varies. For example, two or more papers with different amounts of the composition can be used, both sides of the paper, one of which has a lower amount, making coating application easier. With any of the above combinations, it was unexpectedly found that the mainstream smoke volume was reduced to an extremely low level. "Extra unexpectedly" the application of the treatment composition to cigarette paper / wrapping paper would also have the same effect on the reduction of mainstream smoke. It should be noted that depending on the way the composition is used and applied to a cigarette, various processing aids or mixtures thereof can be used to assist the specific application of the processing composition. Such processing aids include ply materials such as polyvinyl alcohol, starch, carboxymethyl cellulose (CMC), casein and other forms of acceptable adhesives, different forms of bound clay, inert filter media, whiteners, Viscosity modifiers, inert fiber materials such as miscellaneous fibers and rhenium / rhenium fibers are described in US Patent Application Serial No. 10 / 242,676 filed on September 13, 2002, and are intended to be incorporated herein by reference. Penetrants can also be used to bring the composition into paper, tobacco and / or filters. The composition can also be diluted with a suitable diluent such as water to form a slurry, which can be spray-coated, roller-coated, air-knife-coated, stick-coated, paddle-coated, printed-coated, Sizing extrusion coating, roller coating, transfer technology coating and similar methods are applied to traditional cigarette paper. 24 200520698 The dosage of the treatment composition on cigarette paper, wrapping paper or the like is preferably between 2.5 grams / square meter and about 125 grams / square meter, and most preferably between 2.5 grams Per square meter to about 100 grams per square meter. In terms of weight, the paper may contain the treatment composition in an amount of about 10% to 500% by weight, and preferably contains the treatment composition in an amount of about 10% to 400%. These amounts are based on a single sheet of paper, and those skilled in the art will understand that the total weights described herein can also be used in two- or multi-layer paper systems. ❿ The treatment composition is generally used in the form of a slurry of a composition, which can be incorporated into the paper during the paper manufacturing process, or coated or wrapped in various coating methods or embedding methods. Buried on or in the surface of paper, tobacco and / or ferries. The average particle size of the slurry of catalyst and auxiliary is preferably between about 1 micrometer and about 30 micrometers, and most preferably between about 1 micrometer and about 5 micrometers.

The amount of the treatment composition to be applied to the cigarette paper / wrapping paper or the like is preferably between 2.5 g / m 2 and about 125 g / m 2, and most preferably between 2.5 g / m 2 Feet to about ιοι g / m². Expressed in terms of weight, the paper may contain the treatment composition in an amount of about 10% to 500q / g (weight ratio), and more preferably in an amount of about 10% to 400% of the treatment composition. These amounts are for a single sheet of paper. The skilled artisan should be able to understand the higher value gaps described herein for total weight for use in a two- or multi-layer paper system. For a single-layer cigarette paper / wrapping paper, the amount of the treatment composition is typically between 5% and 200%, and most preferably between 10% and 100%, based on the weight of the treatment composition. Metal oxide mixtures that selectively contain precious metals are usually used in the form of an aqueous slurry. The composition ' of the dry composition which can be made into a slurry varies depending on its different application (coating, embedding or incorporation). mouth. According to the present invention ' at least one of the various fragrance end compositions of the present invention (in grass, beneficially and in paper and / or wrapping paper) comprises the treatment composition for reducing the composition of at least one L-smoke. For example, the treatment composition can be used in a combination of several different flavors (i.e., 'the fragrance paper and / or wrapping paper and utensils can include the treatment composition', as for tobacco, which is conventional cigarette tobacco). Alternatively, all of the cigarette combinations may include the treatment composition. The ability of the treatment composition to reduce the amount of Huffman analyte in at least one mainstream cigarette without severe cytotoxicity can provide a desired cigarette. This line is confirmed by cytotoxicity tests and mutation tests on mainstream tobacco. The cytotoxicity test was evaluated using a BALB / e3T3 cell line & internal osmium red uptake analysis, and the mutagenicity test was evaluated using an in vitro AMES reverse mutation analysis. Example Fragrant sample 100 (control group) is a conventional cigarette, which contains a Virginian-style herb blend, a traditional cigarette paper / wrapping paper, and a filter. The cigarette is made using a conventional standard cigarette making machine. Incense sample 101 was made from a single embedded cigarette paper / wrapping paper. The cigarette / wrapping paper had a basis weight of 68 g / m2, of which about 43% was a processing composition (i.e., about 29 g / m2), and the remaining weight was linen. The treatment composition is about 44% of ytterbium from ocher (purchased from AMR Technology, Doron 26 200520698 more than Canada) / 56% of Y-type zeolite CBV 720 (purchased from Hokey Valley International Buddhist Company 'Bin State 'United States). The method for preparing this specific treatment composition is disclosed in US Patent Application Serial No. 1 () / 242,675 filed by the applicant on September 13, 2002, the main purpose of which is to add a reference 0.22% ㈣, the weight is calculated based on the total weight of the treatment composition. The treatment composition is introduced in the form of a polymer: a paper supply. The treatment composition in the paper supply was stirred to form a slurry. The pulp is then transferred to a conveyor belt and formed into a layer in a conventional paper-making manner to produce the cigarette paper with embedded incorporation. Once the paper is prepared, the paper is coated with calcium carbonate to improve the color of the paper and its ashing effect. The cigarette paper itself is then prepared with the cigarette paper embedded and incorporated with the same composition (i.e., filter and tobacco mixture) and manufacturing method as the control group cigarette sample 100. Cigarette sample 102 was prepared from a Virginia tobacco blend coated with the treatment composition. The cigarette itself is the same as the cigarette sample 100 of the control group and the control group (that is, the filter and the traditional fragrance paper / wrapping paper), and is used to prepare the cigarette sample of the control group i. It is prepared by the same manufacturing method. The treatment composition is a mixture comprising 44% hafnium / zirconium (75/25) (purchased from AMR Technology Corp. 'Toronto, Canada) and 56% Y-type zeolite CBV 720 (purchased from Hokey Sanhe International Zeolite, Pennsylvania, USA), the zeolite is doped with 0.125% palladium (the weight is relative to the zeolite). In a conditioning trough, about 76% of the treatment composition (based on the weight of the tobacco) was sprayed into the tobacco blend. 27 200520698 Fragrance terminal sample 103 was prepared from a Virginian-type terminal grass blend incorporating the treatment composition. The cigarette itself has the same composition as the control group cigarette sample 1000 (i.e., a filter and a conventional cigarette paper / wrapping paper), and is prepared by the same manufacturing method as the control group cigarette sample 100. Where

The physical composition is a mixture comprising 44% hafnium / zirconium (75/25) (purchased from AMR Technology Corporation 'Toronto, Canada) and 56/0 Y-type zeolite Cbv 720 (speaking from Hokey Valley International Zeolite) Company, Pennsylvania, USA). The method for preparing this specific treatment composition is disclosed in the U.S. Patent Application Serial No. 10 / 242,675 filed by the applicant on September 13, 2002, the main purpose of which is for reference. About 0.22% of palladium was also added to the composition, and the weight was calculated based on the total weight of the treatment composition. In a conditioning container, about 5% of the treatment composition (based on the weight of the tobacco) is sprayed into the tobacco mixture. The following examples are quantitative analysis based on the official parity method published by the Canadian Health Insurance Agency. The standard methods are: Method T-104: Determine the amount of specific carbonyl compounds in mainstream cigarettes, M ”Developed by the Canadian Health Insurance Agency on December 31, 2011. Method T-114: Determine the amount of phenol compounds in mainstream tobacco, 1999 Established by the Canadian Health Insurance Agency on January 31, 2010. Example 1 This example is used to analyze the amount of carbon monoxide in mainstream cigarettes, especially Fragrant End 28 200520698 Sample 1 0 0 is incorporated and embedded in paper / wrapping paper A cigarette sample of this treatment composition was 101. While performing the above analysis, the amount of sidestream smoke was analyzed at the same time. The amount of sidestream smoke was expressed on a scale of 10 to 8, where 0 represents almost no sidestream smoke, and 8 represents the amount of sidestream smoke produced by a traditional incense end. Quite a number of experimental results in this field show that there is a linear relationship between the gross reading of sidestream smoke and the amount of coal char remaining in sidestream smoke. Generally speaking, For the control of sidestream smoke, it is preferable to have a visual reading of about 2 or below. Although it is known that in some cases, readings higher than 2 can be accepted, for example, when the main purpose is When the mainstream smoke volume is to be reduced. In the following Example 3, The smoke system is relatively quantified. Table 1 Cigarette types 100 (control group) 101 (亳 grams / cigarette) Mainstream smoke composition _ — ^^ One coal coke _ ——— ^ 1 — — — 3.6 __ nicotine 0.67 0 ^ 7 ^ Carbon monoxide ~~~ _ yj · d / ___ 4.1__ —- ^ ___ Sidestream smoke composition 1 eye visible sidestream smoke 8.0 2.0 Compared to the control group, the treatment composition in incense end paper / wrapping paper Can reduce the amount of coal coke, but in fact the coal coke amount was originally expected to increase due to the decrease in the porosity of the paper. Secondly, the decrease in the porosity of the paper should generate a higher amount of carbon monoxide, but the test results of 29 200520698 showed that the results were in line with the expected results. In contrast, the treatment composition will reduce the carbon monoxide content in mainstream smoke. Example 2 This example is used to analyze the analyte content of the carbonyl group and phenol group in mainstream smoke, especially the cigarette sample 100 in Example 1. Cigarette samples that were incorporated into the cigarette paper / wrapping paper and embedded with the treatment composition 1 0 1.

It was originally expected that as the amount of coal coke decreases, the relative content of carbon monoxide should increase due to the catalytic oxidation of the oxidation catalyst that can supply and store oxygen. The content is almost dimensional. This indicates that the amount of carbon monoxide in mainstream smoke is generally lower than expected. Because the amount of rolled carbon is not as high as the control group, it increases accordingly. Therefore, specific Huffman analytes It is also expected to increase with the decrease in coal coke 33 200520698 (due to the catalytic oxidation of the metal oxide type oxidation catalyst that can supply and store oxygen). But the above conclusion It is shown that the treatment composition in tobacco will substantially reduce the amount of specific Huffman analytes in mainstream smoke, because the overall content is slightly reduced.
