Definitions
- the present invention relates to a cigarette filter and a cigarette provided with the same, and more specifically, to a cigarette filter excellent in efficiency of removing nitrogen oxides (NOx) in the mainstream smoke and a cigarette provided with the same.
- NOx nitrogen oxides
- Jpn. Pat. Appln. KOKAI Publication No. 2002-119270 discloses a tobacco filter in which a procyanidin is incorporated in filaments that form the filter.
- the conventional tobacco filters are not capable of removing NOx from the mainstream smoke to a satisfactory degree.
- a cigarette filter comprising a cigarette filter material to which 2-phenyl-4,4,5,5-tetramethylimidazoline-3-oxide-1-oxyl is added.
- a cigarette provided with a cigarette filter according to the present invention.
- FIG. 1 is a graph showing the reduction rate of NO in the mainstream smoke of cigarettes manufactured in Example 1, which will be described later in detail, together with that of a comparative example;
- FIG. 2 is a graph showing the reduction rate of NO in the mainstream smoke of cigarettes manufactured in Example 2, which will be described later in detail, together with that of a comparative example;
- FIG. 3 is a graph showing the reduction rate of NO in the mainstream smoke of cigarettes manufactured in Example 3, which will be described later in detail, together with that of a comparative example;
- FIG. 4 is a graph showing the reduction rate of NO in the mainstream smoke of cigarettes manufactured in Example 4, which will be described later in detail, together with that of a comparative example.
- a cigarette filter according to the present invention comprises a cigarette filter material to which 2-phenyl-4,4,5,5-tetramethylimidazoline-3-oxide-1-oxyl (PTIO) is added.
- PTIO 2-phenyl-4,4,5,5-tetramethylimidazoline-3-oxide-1-oxyl
- PTIO an effective ingredient for removing nitrogen oxides
- PTIO is a compound known per se (see, for example, Jpn. Pat. Appln. KOKAI Publication No. 9-43153).
- cellulose acetate fiber tow In the cigarette filter of the present invention, use may be made, as the filter material, of cellulose acetate fiber tow, filter paper and porous particulate carrier such as activated carbon.
- PTIO can be added by spraying PTIO onto the fiber tow.
- PTIO can be impregnated into the filter paper.
- the filter material thus obtained can be wrapped with a wrapper by an ordinary method, and connected to an end of a cigarette.
- PTIO is impregnated in the porous particulate carrier, and then the thus obtained PTIO-carrying particles are filled in a cavity as is known in the art or added to a tow. More specifically as to the cavity filling, a plain filter is provided to either end of a filter wrapper paper pipe. The PTIO-carrying particles are filled in the cavity between these plain filters.
- the addition to the tow is carried out by a method similar to that used for charcoal filters of commercially available cigarettes, that is, the PTIO-carrying particles are dispersed between the fibers of the acetate filter.
- PTIO is added preferably in an amount of 3 to 10 parts by weight, particularly preferably, 5 to 7 parts by weight based on 100 parts by weight of the filter material. PTIO significantly reduces the amount of NO and NOx contained in the cigarette mainstream smoke even under wet conditions, which are equivalent to the actual smoking conditions.
- PTIO available from Wako Pure Chemical Industries, Ltd.; CAS: 18390-00-6
- PTIO ethanol solutions having a concentration of 0.4% by weight, 1.2% by weight, 2% by weight and 4% by weight, respectively.
- 1 g of coconut shell activated carbon available from Japan Envirochemicals Ltd; a specific surface area: about 1200 m 2 /g
- the PTIO-impregnated activated carbon obtained using the ethanol solution having a PTIO concentration of 0.4% by weight was impregnated with PTIO in an amount corresponding to 1% of the weight of activated carbon (PTIO-impregnated activated carbon I)
- the PTIO-impregnated activated carbon obtained using the ethanol solution having a PTIO concentration of 1.2% by weight was impregnated with PTIO in an amount corresponding to 3% of the weight of activated carbon (PTIO-impregnated activated carbon II)
- the PTIO-impregnated activated carbon obtained using the ethanol solution having a PTIO concentration of 2% by weight was impregnated with PTIO in an amount corresponding to 5% of the weight of activated carbon (PTIO-impregnated activated carbon III), and the PTIO-impregnated activated carbon obtained using the ethanol solution having a PTIO concentration of 4% by weight was impregnated with PTIO in an amount corresponding to 10% of the
- Filter plugs in which PTIO-impregnated activated carbons obtained above were cavity-filled were attached to one-end sides of the tobacco rods respectively.
- the filter plugs had a plain filter (made of cellulose acetate fiber tow) having a length of 5 mm provided on both ends of each plug and 0 mg, 50 mg, 100 mg and 200 mg of PTIO-impregnated activated carbon particles were filled at closest packing.
- the plugs had no ventilation holes.
- the cigarette samples obtained above were set on a smoking machine (RM 26 available from Borgwaldt GmbH), and were burnt under the following conditions.
- the NO and NOx reduction rates were calculated based on the NO and NOx delivery amounts per cigarette obtained similarly for a plain cigarette without the filter connected thereto.
- the NO reduction rate (%) of each sample was illustrated in FIG. 1 .
- a line indicates the results obtained in the case where the PTIO-impregnated activated carbon I was used
- a line b indicates the results obtained in the case where the PTIO-impregnated activated carbon II was used
- a line c indicates the results obtained in the case where the PTIO-impregnated activated carbon III was used
- a line d indicates the results obtained in the case where the PTIO-impregnated activated carbon IV was used
- a line e indicates the results obtained in the case where the activated carbon with no PTIO impregnated was used.
- the filters that contain PTIO-impregnated activated carbon particles significantly reduce the amount of NO as compared to the activated carbon particles that do not contain PTIO.
- the activated carbons carrying 3 to 10% by weight of PTIO have a remarkably high NO reduction effect. It should be noted that the NOx reduction rate exhibited a tendency similar to those of the above-described NO reduction rates.
- PTIO-impregnated activated carbon II prepared in Example 1 was subjected to moisture absorption until it reaches the equilibrium at a temperature of 22° C. and a relative humidity of 60%, and thus moisture-absorbed PTIO-impregnated activated carbon III was obtained.
- Cigarettes were manufactured as in Example 1 except that the moisture-absorbed PTIO-impregnated activated carbon III was used, and the NO reduction rate in the mainstream smoke was obtained. The results were illustrated in FIG. 2 .
- a line a indicates the results obtained in the case where the moisture-absorbed PTIO-impregnated activated carbon III was used
- a line b indicates the results obtained in the case where activated carbon obtained by similar moisture absorption except that PTIO was not impregnated.
- Example 1 The cigarette samples manufactured in Example 1 were burnt under the same conditions as in Example 1 except that the smoke suction volume was changed to 35 mL/puff. Cigarette samples using activated carbon not impregnated with PTIO were burnt also at a smoke suction volume of 35 mL/puff. The NO reduction rate in the mainstream smoke was calculated. The results are illustrated in FIG. 3 .
- a line a indicates the results obtained in the case where the PTIO-impregnated activated carbon III was used, and a line b indicates the results obtained in the case where the activated carbon without PTIO was used. From the results shown in FIG.
- Cigarette samples similar to those of Example 2 were burnt under the same conditions as those in Example 3, and the NO reduction rate in the mainstream smoke was calculated.
- the NO reduction rate in the mainstream smoke was calculated.
- the results were illustrated in FIG. 4 .
- a line a indicates the results obtained in the case where the PTIO-impregnated activated carbon was used
- a line b indicates the results obtained in the case where the activated carbon without PTIO was used. From the results shown in FIG.
- the cigarette filter of the present invention can efficiently remove nitrogen oxides from the tobacco mainstream smoke.
