摘要:A method of producing a fluoroolefin includes contacting a compound of formula (1), RfCX1â•?CHCF3, with a fluorinated ethylene compound of formula (2), CX2X3â•?CX4X5 in the presence of a catalyst. In the compound of formula (1), Rf is a linear or branched C1-C10 perfluorinated alkyl group and X1 is H, Br, Cl, or F. In the compound of formula (2), X2, X3, X4, and X5 are each independently H, Br, Cl, or F and at least three of X2, X3, X4, and X5 are F. The resulting composition comprises a compound of formula (3), Rf(CF2)nCX6â•?CH(CF2)mCX7X8CFX9X10. In the compound of formula (3), X6, X7, X8, X9, and X10 are each independently H, Br, Cl, or F, and the total number of each of H, Br, Cl, and F corresponds to the total number of each of H, Br, Cl, and F provided by the compounds of formulae (1) and (2).

摘要:In an embodiment, a method of producing a fluoroolefin comprises coupling 3,3-dichloro-1,1,1,2,2-pentafluoropropane (CF3—CF2—CHCl2) in a liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CHâ•?CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises coupling 1,1,1-trichloropentafluoropropane (CF3—CF2—CCl3) in a vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3—CF2—CClâ•?CCl—CF2—CF3). The method may further include forming the CF3—CF2—CCl3 in a vapor phase from CF3CF2CHmCl3-m and chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene with hydrogen (H2) in a vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CHâ•?CHCF2CF3 and 3-chloro-1,1,1,2,2,5,56,6,6-decafluoro-3-hexene (CF3CF2CClâ•?CHCF2CF3).
