Procedure

The known methods of producing 1,1,1,3,3-pentafluoropropane are as follows. Carbon tetrachloride and vinylidene chloride are prepared and an addition reaction is triggered. The reaction product, 1,1,1,3,3,3-hexachloropropane, is fluorinated to produce 1,1,1,3,3-pentafluoro-3-chloropropane which is reduced with hydrogen to produce 1,1,1,3,3-pentafluoropropane (WO 95/04022).
