    • A method is proposed for producing 1,1,1,3,3-pentafluoropropane, in which 1,1,3,3,3-pentafluoropropene is reduced at a temperature between 40.degree. C. and 300.degree. C. by reacting it with hydrogen in a gas phase in the presence of a palladium catalyst. Further, a method is proposed for producing 1,1,1,3,3-pentafluoropropane and/or 1,1,3,3,3-pentafluoropropene, in which the raw material 2-chloro-1,1,3,3,3-pentafluoropropene is hydrogenated especially at a temperature between 30.degree. C. and 450.degree. C. in the presence of a catalyst composed of at least one metal selected from palladium, platinum and rhodium. Further, a method is proposed of producing 1,1,3,3,3-pentafluoropropene, in which 1,1,1,3,3-pentafluoro-2,3-dichloropropane is dechlorinated by using hydrogen in the presence of a metal oxide catalyst. Based on these production methods, 1,1,1,3,3-pentafluoropropane and/or 1,1,3,3,3-pentafluoropropene can thus be produced with high yield rates.
