Abstract: 1,1,1,2-tetrafluoroethane (134a) is prepared by reacting, in the gas phase, trichloroethylene with 1,1,1-trifluorochloroethane (133a) and hydrofluoric acid with trichloroethylene/133a molar ratios ranging from 5/95 to 50/50, in the presence of a catalyst consisting of Cr.sub.2 O.sub.3 carried on AlF.sub.3.The process provides 134a yields higher than 90% and permits an exceptionally long life of the catalyst. In this way it is possible to realize a continuous process by recycling the unreacted trichloroethylene and 133a, thereby making up for the relatively low global conversion of the reagents.

Abstract: The invention relates to a method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of fluorinating pentachloroacetone by hydrogen fluoride in the presence of a fluorination catalyst. This fluorination may be conducted in a liquid phase in the presence of an antimony compound as the fluorination catalyst. Alternatively, the fluorination may be conducted in a gas phase in the presence of a fluorination catalyst which may be a fluorinated alumina or at least one compound of at least one metal selected from Al, Cr, Mn, Ni, and Co. The method is suited to an industrial scale production of 3,3-dichloro-1,1,1-trifluoroacetone. The invention further relates to another method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of purifying a crude 3,3-dichloro-1,1,1-trifluoroacetone by a distillation in the presence of water, thereby to produce 3,3-dichloro-1,1,1-trifluoroacetone which is substantially free of organic matters other than 3,3-dichloro-1,1,1-trifluoroacetone. This crude 3,3-dichloro-1,1,1-trifluoroacetone may be the reaction products of the fluorination of pentachloroacetone in a gas phase. Due to the provision of the another method, 3,3-dichloro-1,1,1-trifluoroacetone can be produced with high yield.
