Abstract
"A METHOD FOR PRODUCING ETHYLENE BICLORIDE", of an increased pressure reaction containing a circulating liquid medium comprising a liquid selected from chlorinated hydrocarbons containing two carbon atoms, and mixtures thereof, and maintained at a temperature below the purity of evaporation of the medium at the pressure existing in the reaction zone and which forms unrefined liquid ethylene bichloride, passing the unrefined liquid ethylene bichloride with the circulating medium to a zone of reduced pressure maintained at a pressure and temperature with which which impure ethylene dichloride evaporates by means of the reaction heat of chlorine and ethylene, passing the evaporated imputed ethylene dichloride to a rectification zone and rectifying the vaporized ethylene dichloride by means of the reaction heat of chlorine and ethylene, recovering the purified ethylene bichloride from the rectification zone, while simultaneously making vol view the circulating liquid medium from the reaction zone.
