Abstract:
An object of the present disclosure is to provide a method for producing HCFC-142, which is a target product, with high yield and high efficiency, by preventing the decomposition of starting materials, such as HCC-140 and HCO-1130. A method for producing HCFC-142, comprising bringing a chlorine-containing compound into contact with hydrogen fluoride in the presence of a stabilizer to perform at least one fluorination reaction, thus obtaining a reaction gas containing HCFC-142, hydrogen chloride, and hydrogen fluoride.
