Monohalogenated olefins are prepared from halo-alkanes containing 2 to 6 carbon atoms and at least two hydrogen atoms on adjacent carbons by dehydrogenation of the halo-alkanes at a temperature from about 400 DEG to about 700 DEG C. in the presence of oxygen and in contact with a catalyst comprising a halide of copper and an alkali metal phosphate, particularly potassium phosphate, deposited upon an inorganic support. Typically, vinyl chloride is prepared from ethyl chloride.
