The present invention is directed to a process for preparing 1,1,1-trifluorochloroethane by reacting, in a gas phase, trichloroethylene and hydrogen fluoride. When the reactant gases are diluted with a gas which is inactive to the reaction, it is very easy to control the reaction temperature, and when gas generated from the reaction of 1,1,1-trifluorochloroethane and hydrogen fluoride is used as a diluent gas, generation of 1,1- difluoroethylene is suppressed to a very low level while not influencing the reaction between trichloroethylene and hydrogen fluoride. The 1,1,1-trifluorochloroethane prepared by the process of the present invention is used as a refrigerant.
