Abstract

794,408. Chlorinated aliphatic hydrocarbons. CHEMPATENTS, Inc. Oct. 26, 1956 [Oct. 31, 1955], No. 32650/56. Drawings to Specification. Class 2 (3). In the preparation and recovery of chlorinated hydrocarbons (especially perchloroethylene and carbon tetrachloride) and hydrogen chloride by the thermal chlorination of aliphatic hydrocarbons having 1 to 3 carbon atoms or partial chlorination derivatives thereof, the hot exit gases from the reaction are rapidly quenched by contacting such gases with a liquid hexahaloethane having a molecular weight in the range 170 to 190 and in which the halogen substituents are chlorine and fluorine. Hexahaloethanes specified are 1,2-dichloro-1,1,2,2- tetrafluoroethane and 1,1-dichloro-1,2,2,2-tetrafluoroethane, and the preparation and recovery of perchloroethylene by the thermal chlorination of a mixture of propylene and propane containing small quantities of methane, ethane and an inert gas, using 1,1-dichloro-1,2,2,2- tetrafluoroethane as a quench liquid is fully described with the aid of a drawing.
