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 8):
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 a chromium oxyfluoride catalyst in the vapor phase at a temperature between 100\u00b0 C. and 450\u00b0 C. to produce a product composition including HFO-1234ze, the product composition additionally including 3,3-dichloro-1,1-difluoropropene (HCFO-1232zc).
