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: CX3 CH2 CHX2 wherein X represents fluoro (F) or chloro (Cl), 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. |
