Abstract
The present invention provides a process for preparing a fluorine-containing halogenated hydrocarbon compound by fluorinating, in a reaction field where an antimony halide compound represented by the general formula:SbClpF5−p  (I)wherein p is a value within a range from 0 to 2, and hydrogen fluoride and a halogenated hydrocarbon compound as a raw material exist, the halogenated hydrocarbon compound in a molar ratio of the antimony halide compound to hydrogen fluoride within a range from 40/60 to 90/10. According to this process, a fluorine-containing halogenated hydrocarbon compound (HFC), which is important as a substitute compound of CFC or HCFC, can be prepared economically advantageously with good selectivity while suppressing a corrosive action of a reaction vessel.
