Patent ID: 8445735

Claim:
A method for producing a fluoropropene of formula CF 3 CX═CX 2 wherein each X is F or H, at least one X is H, and at least one X is F, comprising: pyrolyzing a hydrofluorochloropropane of formula CF 3 CXYCX 2 Y, wherein each X is F or H, at least one X is H, and at least one X is F, and one Y is Cl and the other Y is H, and where the hydrofluorochloropropane is not CF 3 CFClCH 3 , in the gas-phase in a reaction vessel, maintained at a temperature high enough to effect the pyrolysis of said hydrofluorochloropropane to said fluoropropene, wherein the selectivity for the production of the fluoropropene is at least 80%, in the absence of a catalyst.
