Patent ID: 7687670

Claim:
A process for the co-manufacture of 1,2,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluoropropene comprising: dehydrofluorinating a blend of 1,1,1,2,3,3-hexafluoropropane and 1,1,1,2,3-pentafluoropropane in a reaction zone having a catalyst, thereby forming a product mixture comprising said 1,2,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluoropropene, unreacted hydrofluorocarbons and hydrogen fluoride, and separating said blend of 1,2,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluoropropene from hydrogen fluoride and said unreacted hydrofluorocarbons to produce 1,2,3,3,3-pentafluoropropene and 2,3,3,3-tetrafluroropropene.
