Abstract:
A method for producing 1,3,3,3-tetrafluoropropene (HFO-1234ze, or 1234ze) from 1-chloro-3,3,3-trifluoropopene (HCFO-1233zd, or 1233zd). In one embodiment, HFO-1233zd is subjected to a disproportionation reaction in the presence of a catalyst at an elevated temperature to produce HFO-1234ze as well as 3,3-dichloro-1,1-difluoropropene (HCFO-1232zc). The catalyst may be at least one of a chromium oxyfluoride catalyst, a chromium oxide catalyst, or a metal fluoride catalyst. The reaction may be conducted in the vapor phase at a temperature between 100° C. and 450° C. Advantageously, in the present method, substantially no hydrogen fluoride (HF) is used as a reactant, and substantially no HF is produced as a product.

Claim (Index 1):
A method for producing 1,3,3,3-tetrafluoropropene (HFO-1234ze), comprising the steps of:\n providing a reactant composition including 1-chloro-3,3,3-trifluoropopene (HCFO-1233zd); and reacting the reactant composition in the presence of at least one catalyst selected from the group consisting of chromium oxyfluoride, chromium oxide, metal fluoride, and combinations thereof at catalyst in the vapor phase at an elevated temperature to produce a product composition including HFO-1234ze.
