摘要： A process for the synthesis of hydrocchlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the steps of fluorination of hydrochloropropenes or hydrochloropropanes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, catalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes. The process produces 1,1, 1,2- tetrafluoropropene (HFO-1234yf) from "feedstock" such as tetrachloropropenes, 1,1,2,3 tetrachloropropene (HCO-1230xa) and/or 1,1,1,2 tetrachloropropene (HCO-1230xf) or pentachloropropanes, HCC-240db, HCC-240aa and/or HCC-240ab which are precursors of the tetrachloropropenes. The process of the present invention comprises the steps of: a) liquid phase or gas phase fluorination of tetrachloropropene (which may be formed via gas phase fluorination of pentachloropropane), in the presence or absence of homogenous or heterogeneous catalyst; to form the intermediate product HCFO- 1233xf and thereafter b) gas phase, catalytic fluorination of the intermediate HCFO-1233xf to form the hydrofluoropropene product 1,1,1,2-tetrafluoropropene (HFO-1234yf).
