Abstract:
A process for the production of perchloroethylene from carbon tetrachloride and from C.sub.1 -C.sub.3 hydrocarbons, which are optionally partially chlorinated, this process comprising the steps of:a) production of perchloroethylene by passing carbon tetrachloride, C.sub.1 -C.sub.3 hydrocarbons, which are optionally partially chlorinated, and chlorine into a reaction plant maintained at a temperature of from 500 to 700.degree. C. and involving a residence time of from 5 to 25 s, the amount of chlorine introduced into the reactor being controlled so as to maintain a chlorine concentration of from 3.5 to 6 mol % at the reactor outlet,b) separation of the perchloroethylene produced from the mixture of reaction products obtained in step a), andc) recycling of the residual carbon tetrachloride and chlorine into the reaction plant of step a).
