Olefinic and chlorinated hydrocarbons are produced by passing a mixture of a hydrocarbon, hydrogen chloride and oxygen or an oxygen containing gas, e.g. air, over a catalyst containing an iron cation and a phosphate anion at an elevated temperature, e.g. 300-650 DEG C. The catalyst may be any iron phosphate and may be modified by the use in conjunction with the iron of one or more of the metals nickel, cobalt, copper, chromium, tin, lead, cerium, magnesium bismuth, manganese, cadmium, vanadium and all metals of Group I-IV of the Periodic Table. The catalyst may be supported on any inert carrier, e.g. silica, alumina, clay, pumice, asbestos and porous brick. Molar ratios of hydrocarbon to oxygen of 1:1 to 10:1 and hydrogen chloride to oxygen of 0.5: 1 to 5: 1 are specified. The examples describe the preparation of ethylene, ethyl chloride and dichloroethane from a hydrocarbon feed of ethane.ALSO:Olefinic and chlorinated hydrocarbons are produced by passing a mixture of a hydrocarbon, hydrogen chloride and oxygen or an oxygen containing gas, e.g. air, over a catalyst containing an iron cation and a phosphate anion at an elevated temperature, e.g. 300-650 DEG C.
