Abstract
Monosubstituted saturated lower hydrocarbons are oxyhalogenated selectively to saturated dihalohydrocarbons at 180.degree.-350.degree. C. in the presence of a catalyst which is formed by depositing a variable valence metal compound on a zeolitic support in such a manner that the catalyst can be employed to selectively produce ethylene dichloride and ethylene from ethyl chloride.

A process for selectively converting a monosubstituted saturated lower hydrocarbon to a saturated dihalohydrocarbon and the corresponding alkene, comprising contacting in the vapor phase reactants consisting essentially of oxygen, a monosubstituted saturated lower hydrocarbon having a non-hydrogen substituent selected from the group consisting of Cl, Br, F, and I;
- and a hydrogen halide, in the presence of a catalyst at a temperature in the range from about 200.degree. C. to about 300.degree. C. and under reaction conditions such that a saturated dihalohydrocarbon and the corresponding alkene are selectively produced;
- said catalyst consisting essentially of (1) at least one compound including copper atoms and chlorine atoms in the form of chloride, and (2) at least one zeolite.

A process for selectively converting ethyl chloride to ethylene dichloride and ethylene, comprising contacting in the vapor phase reactants consisting essentially of ethyl chloride, oxygen, and a hydrogen halide, in the presence of a catalytic amount of a catalyst consisting essentially of copper chloride, a zeolite, potassium chloride, and a silica binder;
- said contacting occurring at a temperature in the range from about 200.degree. C. to about 300.degree. C. and under other reaction conditions such that ethylene dichloride and ethylene and are selectively produced.
