Abstract
Chlorofluorinated aliphatic ketones may be effectively produced by an oxychlorofluorination process by reacting a gaseous mixture of a starting material selected from an aliphatic ketone and a halogenated aliphatic ketone in which the halogen atoms are selected from chlorine and fluorine, or mixtures thereof, an oxygen-containing gas, a chlorinating agent selected from the group consisting of HCl and Cl.sub.2 and mixtures thereof, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier.

The process for the production of chlorofluorinated ketones by the oxychlorofluorination of ketones which comprises reacting a gaseous mixture of a starting material selected from an acyclic or cyclic saturated aliphatic ketone containing only C, H and O atoms and halogenated derivatives thereof in which one or more hydrogen atoms but not all are replaced with halogen atoms selected from chlorine and fluorine, or mixtures thereof, at least .25 mole oxygen in an oxygen-containing gas per C--H bond in the starting material, at least 0.25 mole HCI or equivalent of Cl.sub.2 for each C--H bond present in the starting material, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier, with the weight percentage of cation in the Deacon catalyst ranging from about 0.6-20 based on the total cation content of the Deacon catalyst and metal salt carrier, at elevated temperatures and with a contact time of about 1.--20 seconds.
