Patent ID: 7312367

Claim:
A process for the manufacture of 1,1,3,3,3-pentafluoropropene comprising a) reacting 1,1,1,3,3,3-hexachloropropane with hydrogen fluoride, in the presence of a fluorination catalyst to thereby produce a product comprising 1,1,1,3,3,3-hexafluoropropane and optionally additionally 1-chloro-1,1,3,3,3-pentafluoropropane; and then b) reacting the 1,1,1,3,3,3-hexafluoropropane and optionally additionally 1-chloro-1,1,3,3,3-pentafluoropropane, with a caustic under conditions sufficient to dehydrofluorinate 1,1,1,3,3,3-hexafluoropropane and optionally additionally dehydrochlorinate 1-chloro-1,1,3,3,3-pentafluoropropane, to form a reaction product which comprises 1,1,3,3,3-pentafluoropropene.
