Abstract
A major amount of 1,2-dichloroethane (D12) and lesser amounts of trichloroethane and tetrachloroethane are prepared by contacting carbon tetrachloride, ethylene and oxygen (or an oxygen-containing gas, notably air) with an oxychlorination catalyst at a temperature sufficient to produce D12, and thereafter separating such D12 from the products of reaction.
