Procedure

A method of producing 1,1,1,3,3-pentafluoropropane which comprises reacting 1,1,1,2,2,3,3-heptachloropropane with an alkali metal hydroxide in the presence of a phase transfer catalyst to form 1,1,1,2,3,3-hexachloropropene; continuously reacting, at a constant pressure and in the liquid phase, 1,1,1,2,3,3-hexachloropropene with excess hydrogen fluoride in the presence of at least one of an antimony trihalogenide and an antimony pentahologenide while selectively removing 1,1,1,3,3-pentafluoro-2,3-dichloropropane as it is formed; and reacting gaseous 1,1,1,3,3-pentafluoro-2,3-dichloropropane with hydrogen in the presence of a noble metal catalyst.
