Abstract

As-dichloroethylene is obtained by the action of iron, zinc or cadmium in finely-divided form and water on asymmetric tetrachlorethane, at raised temperature. According to the examples, the reaction is performed with zinc powder in the aqueous phase, and with iron turnings in the vapour phase, at temperatures between 50--100 DEG C.
