A METHOD OF PRODUCING 1,1,1,3,3-PENTAFLUOROPROPANE, A METHOD OF PRODUCING 1,1,1,3,3-PENTAFLUORO-2-HALOGENO-3-CHLOROPROPANE, AND A METHOD OF PRODUCING 1,1,1,2,3,3-HEXACHLOROPROPENE

摘要

There are provided production methods of 1,1,1,3,3-pentafluoropropane characterized in that 1,1,1,3,3-penta-fluoro-2,3-dichloropropane is reacted with hydrogen fluoridein the presence of a noble metal catalyst; of 1,1,1,3,3-pentafluoro-2-halogeno-3-chloropropane characterized inthat the halogenated propene indicated as general formulaI is fluorinated in the presence of antimony trihalogenideand / or antimony pentahalogenide by hydrogen fluoride ofmole ratio of or over five times the said antimonyhalogenide in a liquid phase; and of 1,1,1,2,3,3-hexachloro-propene characterized in that 1,1,1,2,2,3,3-heptachloro-propane is reacted with an aqueous solution of alkali metalhydroxide in the presence of a phase transfer catalyst.Therefore, an industrial manufacturing method which ispossible to obtain the objective product easily at low costand high yield can be provided.3 5
