<p>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 characterised 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 to 120 DEG C, and the product is separated from the reaction mixture by fractional distillation.</p> |
