PROCESS FOR PRODUCING 1,1,1,3,3-PENTAFLUOROPROPANE, PROCESS FOR PRODUCING 1,1,1,3,3-PENTAFLUORO-2-HALOGENO-3-CHLOROPROPANE, AND PROCESS FOR PRODUCING 1,1,1,2,3,3-HEXACHLOROPROPENE

摘要

A process for producing 1,1,1,3,3-pentafluoropropane by the reaction of 1,1,1,3,3-pentafluoro-2,3-dichloropropane with hydrogen fluoride in the presence of a noble metal catalyst; a process for producing 1,1,1,3,3-pentafluoro-2-halogeno-3-chloropropane by the liquid-phase fluorination of a halogenopropene of general formula (I) (wherein X and Y represent each C1 or F) in the presence of antimony trihalide and/or antimony pentahalide with at least five times by mole as much hydrogen fluoride as the antimony halide; and a process for producing 1,1,1,2,3,3-hexachloropropene by the reaction of 1,1,1,2,2,3,3-heptachloropropane with an aqueous solution of an alkali metal hydroxide in the presence of a phase transfer catalyst. These processes can provide the target products at low cost in high yields on an industrial scale.
