PROCESS FOR DEHYDROFLUORINATION OF 3-CHLORO-1,1,1,3-TETRAFLUOROPROPANE TO 1-CHLORO-3,3,3-TRIFLUOROPROPENE

摘要

A process for making 1-chloro-3,3,3-trifluoropropene. The process has the following step: dehydrofluorinating 3-chloro-1,1,1,3-tetrafluoropropane under conditions sufficient to effect dehydrofluorination in the presence of a catalyst. Preferred catalysts are selected from the group consisting of (i) one or more halogenated trivalent or higher valent metal oxides, (ii) one or more trivalent or higher valent metal halides, and (iii) one or more natural or synthetic graphite materials.
