Method of Hydrodechlorination to Produce Dihydrofluorinated Olefins

Disclosed herein is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents with hydrogen. Also disclosed is a catalyst composition for the hydrodechlorination of chlorofluoroalkenes comprising copper metal deposited on a support.

Process for the preparation of hexafluorobutane, and intermediates thereby obtainable

1,1,1,4,4,4-Hexafluorobutane is prepared by first reacting 1,1,3,4,4-pentachlorobuta-1,3-diene with hydrogen fluoride in the presence of catalysts at 60° to 180° C. to give 1,1,1,4,4,4-hexafluoro-2-chlorobutane, and converting this to 1,1,1,4,4,4-hexafluorobutane. On working up the product of the first stage of the process, it is possible to isolate novel compounds of formula (I): in which X is fluorine or chlorine and R is --CHCl--CF2 Cl, --CHCl--CFCl2 or --CCl=CCl2.
