The present invention provides a method for producing HFC-143 that is inexpensive and more efficient than existing methods. The present invention specifically provides a method for producing 1,1,2-trifluoroethane (HFC-143), which comprises making 2-chloro-1,1-difluoroethane (HCFC-142) and 1-chloroethane - A step in which at least one chlorine-containing compound in 1,2-difluoroethane (HCFC-142a) is brought into contact with hydrogen fluoride to perform one or more fluorination reactions to obtain a reaction gas containing HFC-143, hydrogen chloride and hydrogen fluoride. |
