Abstract
A process for the preparation of 1,1,1-trichlorotrifluoroethane in which 1-chloro-2,2,2-trifluoroethane is subjected to chlorination by bringing the 1-chloro-2,2,2-trifluoroethane into contact with chlorine within a reaction vessel characterized in that the process is conducted in the liquid phase in the presence of a chemical free radical initiator under a pressure of from 1 to 20 bar and at a temperature within the range 50.degree. to 120.degree. C., and the product is separated from the reaction mixture by fractional distillation.
