Abstract:
A method for producing a hydrogen-containing fluorinated hydrocarbon in which hydrogen fluoride as a reaction raw material and at least one halogenated hydrocarbon as a reaction raw material selected from a group consisting of a chlorinated alkene and a hydrogen-containing chlorinated alkane are reacted in the presence of a fluorination catalyst so as to obtain a reaction mixture comprising a reaction product which comprises the hydrogen-containing fluorinated hydrocarbon, which method comprises the steps of:(a) supplying one of the reaction raw materials to a gap between an inner reactor made of a material which is substantially resistant to the reaction and an outer container made of a material which is substantially resistant to at least said one of the reaction raw materials and which is installed outside the inner reactor;(b) supplying said one of the reaction raw materials to the inner reactor;(c) supplying the other reaction raw material to the inner reactor; and(d) reacting said one of the reaction raw materials with the other reaction raw material in the presence of the fluorination catalyst in the inner reactor so as to obtain the reaction product comprising the hydrogen-containing fluorinated hydrocarbon.
