PROBLEM TO BE SOLVED: To provide an inexpensive and more efficient method for producing HFC-143 than a conventional method. A method for producing 1,1,2-trifluoroethane (HFC-143). 1,1,2-Trichloroethane (HCC-140), 1,2-dichloro-1-fluoroethane (HCFC-141), 1,1-dichloro-2-fluoroethane (HCFC-141a), (E, Z) At least one selected from the group consisting of -1,2-dichloroethylene (HCO-1130 (E, Z)) and (E, Z) -1-chloro-2-fluoroethylene (HCFO-1131 (E, Z)). A method for producing HFC-143, which comprises a step of carrying out one or more fluorination reactions by contacting the chlorine-containing compound of HFC with hydrogen fluoride to obtain a reaction gas containing HFC-143, hydrogen chloride and hydrogen fluoride.
