process flow vinyl chloride for ethylene
Production of Vinyl Chloride from Ethylene; Today, vinyl chloride is almost exclusively manufactured by thermal cleavage (dehydrochlorination) of 1,2-dichloroethane (EDC). The feedstock for the thermolysis can be obtained from two routes: 1. By the older method, addition of chlorine to 2. By the more modcrn process, oxychlorination of ethylene ...
In the oxychlorination process, pure ethylene and hydrogen chloride, mixed with oxygen, are reacted at 200-300°C and 4-6 bar in the presence of a catalyst, usually cupric chloride. The reaction takes place in either a fixed bed or fluid bed reactor, the latter being preferred as it is easier to control the temperature.
