Abstract: The continuous production of 1,1-dichloro-1-fluoroethane(HCFC-1416) comprises (a) continuously liquid phase reacting 1,1,1- trichloroethane with an excessive amount of an anhydrous hydrofluoric acid in the reactor at 4-20 bar and 60-130 deg.C., (b) contacting and rectifying the produced gas and the anhydrous hydrofluoric acid to recycle a low volatile material of the anhydrous hydrofluoric acid to the reactor, and to condense an azeotropic mixture of an organic material and the hydrofluoric acid and high volatile material of a hydrochloric acid in the condenser, (c) separating an inorganic layer(HF), an organic layer and a gas layer(HCl) from the liquid-gas mixture in the layer separator, and (d) purifying the exhausted organic layer. The HCFC-1416 is a CFC substitute material
