摘要： 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.

摘要： 1,2-Dichloroethane is prepared by oxychlorination of ethylene in the presence of a catalyst which contains, on a conventional carrier, copper(II) chloride in a concentration such that the amount of copper ions is from 1 to 20% by weight, based on the total weight of the catalyst, by a process in which the catalyst is obtained by impregnating the carrier with an aqueous solution which contains copper(II) chloride and hydrogen chloride in amounts such that the weight ratio of copper ions to hydrogen chloride is from 13:1 to 130:1.

摘要： A process for preparing 1,2-dichloroethane by reacting about 2 mols of ethylene, about 4 mols of hydrogen chloride and about 1 mol of oxygen in the presence of a fixed bed of supported catalyst based on copper(II) chloride in only one reaction zone at a pressure of from 2 to 10 bar and at from 220 to 280° C., separating off 1,2-dichloroethane and water from the reaction mixture emerging from the reaction zone and passing most of the exhaust gas back into the reaction zone, where, prior to entry into the reaction zone, the exhaust gas is mixed with ethylene, hydrogen chloride and oxygen, and the oxygen content of the mixture does not exceed 7% by volume, and where the ethylene content of the gas mixture entering into the reaction zone is regulated so that the exhaust gas comprises less than 20% by volume of ethylene, where the supported catalyst used is obtained by tableting a mixture of pseudoboehmite and &ggr;-Al2O3 in a weight ratio from 4:1 to 1:4, if desired with addition of tableting auxiliaries, loading this support with the active components by saturating with a CuCl2/KCl solution so that the copper content is from 1 to 15% by weight and the potassium content is from 0.1 to 8% by weight, based in each case on the total weight of the catalyst, and then drying the catalyst at from 60 to 400° C.
