Title:
PROCESS FOR PRODUCING 1,1,1,3,3-PENTAFLUOROPROPANE
Document Type and Number:
WIPO Patent Application WO/1997/013737
Kind Code:
A1
Abstract:
A process for producing 1,1,1,3,3-pentafluoropropane (HFC-245fa) which comprises reacting a halogenated propane represented by the following general formula, such as 1,1,1,3,3-pentachloropropane: CX3CH2CHX2 wherein X represents fluoro (F) or chloro (C1), provided that not all Xs represent fluoro at the same time; with anhydrous hydrofluoric acid (HF) in the presence of an antimony catalyst to thereby give HFC-245fa. Thus HFC-245fa can be economically and efficiently obtained via simple steps.
