Abstract: Disclosed is a process for the preparation of cis-1,1,1,4,4,4-hexafluoro-2-butene comprising contacting 1,1,1-trifluorotrichloroethane with hydrogen in the presence of a catalyst comprising ruthenium to produce a product mixture comprising 1316mxx, recovering said 1316mxx as a mixture of Z- and E-isomers, contacting said 1316mxx with hydrogen, in the presence of a catalyst selected from the group consisting of copper on carbon, nickel on carbon, copper and nickel on carbon and copper and palladium on carbon, to produce a second product mixture, comprising E- or Z-CFC-1326mxz, and subjecting said second product mixture to a separation step to provide E- or Z-1326mxz. The E- or Z-1326mxz can be dehydrochlorinated in an aqueous basic solution with an alkali metal hydroxide in the presence of a phase transfer catalyst to produce hexafluoro-2-butyne, which can then be selectively hydrogenated to produce Z-1, 1,1,4,4,4-hexafluoro-2-butene using using either Lindlar's catalyst, or a palladium catalyst further comprising a lantanide element or silver.

Abstract: A process is disclosed for making CF3CF═CHF. The process involves reacting CF3CClFCCl2F with H2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF3CF═CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H2 to CF3CClFCCl2F fed to the reaction zone is between about 1:1 and about 5:1. Also disclosed are azeotropic compositions of CF3CClFCCl2F and HF and azeotropic composition of CF3CHFCH2F and HF.
