ABSTRACT:
A process is provided for the chlorination of ethane using hydrogen chloride, chlorine or 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, and second comprising the vapor phase reaction of hexachloroethane with ethane feedstock to produce chlorinated ethanes, chlorinated ethylenes, and hydrogen chloride.
