Abstract
A method for the oxychlorination of ethylene to produce 1,2-dichloroethane comprises reacting ethylene with a chlorine source and an oxygen source in a fixed-bed oxychlorination reactor in the presence of a catalyst, and is characterized in that a single reactor is used and ethylene is present in a large molar excess with respect to chlorine. The chlorine source is suitably HCl, the catalyst is suitably a cupric chloride catalyst, and the molar excess of ethylene is preferably between 200 and 700%.
