    摘要: A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor. In one configuration, a feed stream comprises a paraffin or olefin hydrocarbon such as methane or ethylene, and a second feed stream comprises oxygen and hydrogen chloride. By segregating these feeds, combustion reactions can be minimized and yields of chlorinated components increased.

    摘要: A process is provided for the production of allyl chloride from three carbon atom hydrocarbons (propane and/or propylene) using hydrogen chloride or hydrogen chloride/chlorine mixtures as the chlorinating agent. The process includes reaction steps operated in tandem in separate zones first comprising the reaction of perchloroethylene with hydrogen chloride and oxygen in the presence of an oxychlorination catalyst to give hexachloroethane and water, second comprising the vapor phase reaction of hexachloroethane with propane/propylene feedstock to produce allyl chloride, perchloroethylene, and hydrogen chloride, and third isolating the products of the second step and repeating the first step using as starting materials the thus isolated perchloroethylene and hydrogen chloride.
