Abstract

Procedure for treating the crude gaseous product from the pyrolysis of 1,2-dichloroethane to vinyl chloride, comprising the following steps: cooling of the gaseous product from the pyrolysis, at a pressure higher than atmospheric pressure, so as to obtain a gas phase and a liquid phase; treatment of this liquid phase with a quantity of chlorine comprised between 0.01 and 5% by weight, in relation to the 1,2-dichloroethane not transformed in pyrolysis; and separation of the obtained mixture, in its different constituents.
