Process for the production of chlorofluorinated aromatic hydrocarbons

摘要

Chlorofluorinated aromatic hydrocarbons may be effectively produced by an oxychlorofluorination process by reacting a gaseous mixture of a starting material selected from an aromatic hydrocarbon and an aromatic hydrohalocarbon in which the halo atoms are selected from chloro and fluoro, or mixtures thereof, an oxygen-containing gas, a chlorinating agent selected from the group consisting of HCl and Cl2 and mixtures thereof, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier.
