    Oxychlorination occurs when hydrogen chloride, produced as a by-product of the thermal cracking of EDC, reacts with ethylene in the presence of catalyst and air (or oxygen), and EDC is again obtained. When EDC from the oxychlorination process is dehydrated and then thermally cracked (together with the EDC from the direct chlorination process), VCM is obtained.
