Abstract
Monohalogenated olefins are selectively prepared in high yields from alkanes having 2 to 4 carbon atoms by the reaction of such hydrocarbons with a hydrogen halide and a source of oxygen at a temperature from about 400.degree. to about 650.degree. C. in contact with a catalyst comprising a copper halide and an alkali metal phosphate, particularly potassium phosphate, deposited on an inorganic support. Typically, vinyl chloride is prepared in one step from ethane.

A process for producing monohalogenated olefins which comprises reacting an alkane having 2 to 4 carbon atoms with a hydrogen halide and a source of oxygen at a temperature in the range from about 400.degree. C. to about 650.degree. C. in contact with a catalyst consisting essentially of a copper halide and an alkali metal phosphate, and optionally from about 0.1% to about 1% by weight of a platinum group metal, deposited upon an inorganic support.
