Abstract
Chlorofluorinated cycloaliphatic hydrocarbons may be effectively produced by an oxychlorofluorination process by reacting a gaseous mixture of a starting material selected from a cycloaliphatic hydrocarbon and a cycloaliphatic 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 Cl.sub.2 and mixtures thereof, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier.
Claims57
The process for the production of chlorofluorinated cycloaliphatic hydrocarbons which comprises reacting a gaseous mixture of a starting material selected from a cycloaliphatic hydrocarbon and a cycloaliphatic hydrohalocarbon in which the halo atoms are selected from chloro and fluoro, or mixtures thereof, at least .25 mole oxygen in an oxygen-containing gas for each C--H bond in the starting material, at least 0.50 mole HCl or equivalent amount of Cl.sub.2 for each C--H bond and C.dbd.C 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 from about 0.1-20 seconds.
The process according to claim 51 in which the Deacon catalyst is CuCl.sub.2.
The process for the production of chlorofluorinated cycloaliphatic hydrocarbons which comprises reacting a gaseous mixture of a starting material selected from a cycloaliphatic hydrocarbon and a cycloaliphatic hydrocarbon in which the halo atoms are selected from chloro and fluoro, or mixtures thereof, at least .25 mole oxygen in an oxygen-containing gas for each C--H bond in the starting material, at least 2 mole HCl or equivalent amount Cl.sub.2 per mole of 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 from about 0.1-20 seconds.
