Abstract

Procedure for the manufacture of chlorinated derivatives of ethylene from ethylene or other chlorinated derivatives thereof, characterized in that chlorine gas containing between 0 and 50% by volume of HC1 gas is used, especially chlorine gas with 10% by volume of HC1 gas, and by the following operative process: In a first stage 1,2 dichloroethane is obtained from ethylene in a reactor filled with Raschig and filled with 1,2 liquid dichloroethane, which works between 15 and 80º and especially at 55ºC and which is fed with Cl2 that contains between 0 and 50% by volume, of HC1 gas and with ethylene, regulating the temperature by means of the feed. Next, 1,2-dichloroethane is dehydrochlorinated to vinyl chloride in a reactor filled with a Cl2Ba catalyst on activated carbon containing between 5-30 % of Cl2Ba (by weight) and especially 25.5% of it referred to total weight, said dehydrochlorinator working between 200-400ºC, and especially at 320ºC, chlorinating the exhaust gases from this reactor in another reactor filled with Raschig and filled with 1,1,2 liquid trichloroethane and passing a stream of Cl2 containing between 0 and 50% by volume of HCl gas at a temperature between 10 and 90ºC and especially at 70ºC. In this reactor, the acetylene produced in the dehydrochlorination of 1,2-dichloroethane is simultaneously chlorinated. The next stage is the dehydrochlorination of 1,1,2 trichloroethane in a reactor filled with Cl2Ba catalyst supported on activated carbon with the concentration indicated above to give 1,1 dichloroethylene, 1-2 trans dichloroethylene and 1-2 cis dichloroethylene, working at a temperature between 200ºC and 400ºC and especially at 290ºC, and the mixture of vapors and gases that comes out of this reactor is chlorinated in another reactor filled with Raschig rings and filled with 1,1,2,2 tetrachloroethane, using Cl2 that has between 0 and 50% by volume of HCl gas, at temperatures between 10º and 90ºC and especially at 35º, said temperature being regulated by means of the reactor feed flows. The dehydrochlorination of 1,1,2,2 and 1,1,1,2 tetrachloroethane is then carried out in a reactor filled with Cl2Ba catalyst on activated carbon with the concentration described in this claim above and at temperatures between 100 and 300ºC, especially at 200ºC, and then the trichlorethylene obtained in a concentration greater than 85% (without previous separations) is chlorinated in a reactor filled with Raschig rings and filled with liquid pentachloroethane passing a stream of Cl2 gas containing between 0 and 50% in volume of HC1 gas, keeping the chlorination temperature between 50 and 110ºC, especially at 100ºC, said temperature being regulated by means of the feed flows and finally the pentachloroethane is dehydrochlorinated in a reactor filled with the mentioned Cl2Ba catalyst on activated carbon and at temperatures between 80º and 300ºC, especially at 150ºC.
