Method for the preparation of 1,1,1,3,3- pentafluoropropene and 1,1,1,3,3-pentafluoropropane

摘要

A method for the production of 1,1,1,3,3- pentafluoropropane which comprises contacting 2,2-dichloro- 1,1,1,3,3,3-hexafluoropropane with hydrogen in the presence of a metal-containing catalyst carried by a carbon support, at a temperature from 300oC to about 800oC. The metal-containing catalyst carried by the carbon support is selected from the group consisting of a metal, metal halide, metal oxide, metal oxyhalide and various combinations. Also the metal of the catalyst is selected from the group consisting of Fe, Cu, Ni and Cr.
