PROCESS FOR FLUORINATNG HALOGENATED HYDROCARBON

摘要

A process for efficiently producing a fluorinated compound by the vapor-phase fluorination or hydrofluorination of a hydrogenated alkane or alkene with hydrogen fluoride in the presence of a catalyst comprising at least one element selected from among Ti, V, Zr, Mo, Ge, Sn and Pb, and alumina, aluminum fluoride or partially fluorinated alumina. The catalyst is prepared by the impregnation method whereby the above element is carried on alumina or the like or the coprecipitation method whereby the target catalyst is coprecipitated from the solution of any of the above aluminum compounds and a compound of any of the above elements.
