The presence of rare earth halides or rare earth oxyhalide catalysts to form halogenated hydrocarbon products such as allyl chloride and optionally olefin co-products such as propene, having at least 3 carbon atoms and having a greater number of halogen substituents than the reactant hydrocarbons Under oxidative halogenation and any dehydrogenation process comprising contacting a reactant hydrocarbon having 3 or more carbon atoms or a halogenated derivative thereof, such as propane or propene, with a halogen source and optionally an oxygen source. In order to maximize the production of the desired product, two less preferred products, halogenated hydrocarbons or olefins can optionally be recycled to the process. |
