Patent ID: 8395001

Claim:
A process for producing 2-chloro-1,1,1,2-tetrafluoropropane, comprising: a chlorination step of reacting 1,2-dichloro-2-fluoropropane and chlorine in the presence of a solvent under irradiation with light to obtain 1,1,1,2-tetrachloro-2-fluoropropane, and a fluorination step of reacting the 1,1,1,2-tetrachloro-2-fluoropropane obtained in the chlorination step and hydrogen fluoride in the presence of a catalyst to obtain 2-chloro-1,1,1,2-tetrafluoropropane, wherein the solvent comprises at least one member selected from the group consisting of carbon tetrachloride, 1,1,2-trichloro-1,2,2-trifluoroethane, a C 5-8 linear perfluoroalkyl compound represented by the formula CF 3 (CF 2 ) n CF 3 , wherein n is an integer of from 3 to 6, and a perhalogenated compound, and wherein the catalyst comprises at least one halide of a metal selected from the group consisting of antimony, niobium, tantalum, tin, titanium, iron and thallium.
