Description

HEXAFLUORO-2-BUTENE COMPOSITIONS, STORAGE AND HANDLING FIELD The invention relates to hexafluoro-2-butene (HFO-1336mzz) compositions, storage and handling. BACKGROUND Hydrofluoroolefins (HFOs) having low ozone depletion potential (ODP) and low global warming potential(GWP) have been replacing saturated CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) in a variety of applications for several years, as well as hydrofluorocarbons which tend to have high GWP values. As a result, these low ODP and GWP materials are used as refrigerants, solvents, foam expansion agents, cleaning agents, aerosol propellants, dielectrics, fire extinguishants, and power cycle working fluids. Many commercial refrigerants include halogenated olefinic compounds. Hydrofluoroolefins (HFOs) and hydrochlorofluoro olefins (HCFOs) have found utility as modern refrigerants due to their low global warming potential (GWP). Olefinic compounds are unsaturated hydrocarbons including one or more pairs of carbon atoms linked by double bond. The unsaturated double bond provides a reactive moiety which is subject to attack by various reactive species. During the transfer, transportation, storage and use, olefinic refrigerants may encounter adverse materials or extremely undesirable conditions that cause the double bond to react to form unwanted by- products, which reduce the refrigerant products’ performance and effectiveness.. Preparation of olefinic refrigerants, including but not limited to 1,1,1,4,4,4 hexfluoro-2-butene (HFO-1336mzz) and mixtures of the Z- and E- isomers have been described in US Patent Publication No.20190248719, the disclosure of which is incorporated herein by reference in its entirety. Z-1,1,1,4,4,4 hexfluoro-2-butene can be isomerized to E-1,1,1,4,4,4 hexfluoro-2-butene, as disclosed in for example U.S. Patent No.10,479,745, the disclosure of which is incorporated herein by reference in its entirety. Z-HFO-1336mzz and E-HFO1336mzz compositions, systems and methods of preparing, transporting, transferring, storing and using these olefinic refrigerants with reduced levels of chlorinated reaction products, moisture and/or NCG components are desired. Thus the need remains for improved production, purification, storage and handling of high purity HFO-1336mzz isomers, e.g., compositions with at least 99% Z- HFO-1336mzz or 99% E-HFO-1336mzz.

If the container was previously filled with 1336mzz(Z), and there is no pressure in the container, then fresh HFO- 1336mzz compositions are directly charged to the previously used container. The container enables distribution, blending, transport, transfer, storage, recovery and usage of the HFO-1336mzz compositions disclosed herein. In one particular embodiment a container has a volume of 500 L to 1000 L, or 750 L to 950 L, or 850 L to 950 L is used for transportation, transfer, and storage, such as that described in US Patent Publication No.20220136748 the disclosure of which is incorporated herein by reference in its entirety. Due to the vertical orientation, the container lends itself to ease of processing of said refrigerant. It should be noted that any vertical cylinder designed for flammable refrigerants, can also be conveniently used for non-flammable refrigerants. Depending on the refrigerant being used in the inventive process, the pressure, flammability and volume will follow the appropriate design codes. In the US for example, the vertical ton tank will follow the ASME design construction and pressure rating, while in the EU the vertical ton tank will follow ADR and in Japan the vertical ton tank will follow HPGL For a new container, a vacuum is first pulled to remove any inert gases before charging. If the container was previously filled with 1336mzz(Z), and there is no pressure in the container, then fresh HFO- 1336mzz compositions are directly charged to the previously used container. The container enables distribution, blending, transport, transfer, storage, recovery and usage of the HFO-1336mzz compositions disclosed herein.

DETAILED DECSRIPTION The present invention relates to HFO-1336mzz isomer compositions containing E-1,1,1,4,4,4 hexafluoro-2-butene (HFO-1336mzz(E)) and Z-1,1,1,4,4,4 hexafluoro-2-butene (HFO-1336mzz(Z), wherein one of the E-isomer or Z-isomer is present in an amount of at most about 0.5 percent and the other isomer is present in an amount of at least 99 percent, based on the total amount of the composition, transportation, transfer, and storage of the composition disclosed herein, and use thereof which involves minimizing/reducing/eliminating the presence of impurities such as chlorine containing species, moisture, and/or NAG/NCG compounds. Before addressing details of embodiments described herein, some terms are defined or clarified as follows. Where a range of numerical values is recited herein, unless otherwise stated, the range is intended to include the endpoints thereof, and all integers and fractions within the range. It is not intended that the scope of the invention be limited to the specific values recited when defining a range. Moreover, all ranges set forth herein are intended to include not only the particular ranges specifically described, but also any combination of values therein, including the minimum and maximum values recited. The term “compound” as used herein is meant to include all stereoisomers, geometric isomers, tautomers, and isotopes of the structures or chemical described. Compounds herein identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified. The term “hydrohaloalkane,” as used herein means a molecule containing hydrogen, carbon, fluorine and/or chlorine and/or bromine and/or iodine, with no carbon- carbon double bond (halo=fluoro, chloro, bromo, iodo). Examples are described throughout the instant specification. The term “hydrohaloalkene” is intended to mean a chemical compound selected from the classes of hydrofluoroolefms (HFOs) and hydrochlorofluoroolefins (HCFOs) which include a double bond between adjacent carbon atoms and can contain 1 to 8 carbon atoms. The term “dehydrohalogenation,” as used herein, means loss of HX from a hydrohaloalkane, where X=F, Cl, Br, I, where H and X are on adjacent carbons in the hydrohaloalkane. For example, the term “dehydrofluorination,” “dehydrofluorinating” or “dehydrofluorinated,” as used herein, means a process during which hydrogen and fluorine on adjacent carbons in a molecule are removed; the term “dehydrochlorination,” “dehydrochlorinating,” or “dehydrochlorinated,” as used herein, means a process during which hydrogen and chlorine on adjacent carbons in a molecule are removed. As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B is true (or present). The transitional phrase “consisting of” excludes any element, step, or ingredient not specified. If in the claim such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consists of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole. The transitional phrase “consisting essentially of” is used to define a composition, method that includes materials, steps, features, components, or elements, in addition to those literally disclosed provided that these additional included materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention, especially the mode of action to achieve the desired result of any of the processes of the present invention. The term ‘consisting essentially of’ occupies a middle ground between “comprising” and ‘consisting of.’ Where applicants have defined an invention or a portion thereof with an open- ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also include such an invention using the terms “consisting essentially of” or “consisting of.” Also, use of “a” or “an” are employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise. As used herein, the term “substantially free” means that less than about 0.0005 percent by weight is present (5 ppm by weight). As used herein the term “about” in certain embodiments can mean ± 1%, ± 2%, ± 3% and up to and including ±10% of an identified value, including all whole numbers and fractions thereof. As used herein the term “substantially,” “main” or “major” should be construed to mean at least 51 percent. In a preferred embodiment, compositions according to the present invention are free of or substantially free of certain Fluorinated Substances which includes any substance that (i) contains at least one fully fluorinated methyl (–CF3) or methylene (– CF2–) carbon atom (without any H/Cl/Br/I attached to it); and (ii) meets the criterion for persistence in soil/sediment and water established in Annex XIII (Section 1.1.1) of the European Union’s REACH Regulation
