Abstract
Copper chloride has been employed as a reagent for oxychlorination of hydrocarbons. It has now been found that a non-halide copper compound in combination with a rare earth compound is an excellent oxychlorination catalyst, e.g. a CuCO.sub.3 - CeO.sub.2 catalyst calcined at 900.degree. C. for 1 hour converted 99 mole % of ethylene fed at a selectivity of 100% to chlorinated products, principally vinyl chloride, ethyl chloride and dichloroethane.
