ABSTRACT:
A process for the preparation of vinyl chloride by vaporizing liquid 1,2-dichloroethane, thermally cracking the 1,2-dichloroethane and cooling the hot reaction mixture by means of cooled and condensed portions of the reaction mixture, wherein a defined amount of the 1,2-dichloroethane is taken off as liquid in or downstream of the vaporizer and mixed with a defined amount of the cooled liquid portion of the reaction mixture, the mixture is distilled and the constituents taken off the top of the distillation column are mixed with the liquid 1,2-dichloroethane upstream of the vaporizer while the constituents taken off the bottom of the distillation column are worked up by distillation.
