Abstract
A method for producing a hydrogen-containing fluorinated hydrocarbon includes supplying HF to a gap between an inner reactor made of a material resistant to the reaction and an outer container made of a material resistant to HF; supplying HF to the inner reactor; supplying a halogenated hydrocarbon selected from a chlorinated alkene and a hydrogen-containing chlorinated alkane to the inner reactor; and reacting HF with halogenated hydrocarbon in the presence of a fluorination catalyst in the inner reactor to obtain the reaction product containing the hydrogen-containing fluorinated hydrocarbon.
