摘要： The invention relates to a method for producing high purity 1,2-dichloroethane using a liquid reaction medium that is circulated and that is essentially composed of 1,2-dichloroethane and a catalyst. At least ethylene and chlorine are added to the reaction medium and a mainly chlorine-containing gas flow is dissolved in a part of the reaction medium which is essentially devoid of dissolved ethylene. The gaseous components not dissolved in this solution are removed from the solution by means of a gas-separation device and the solution from which the undissolved gas components were removed is contacted with ethylene which is present in dissolved form.

摘要： The present invention is directed to a process for preparing 1,2-dichloroethane by reacting ethene with hydrogen chloride and oxygen over a copper-containing fluidized-bed catalyst. The discharge of the catalyst from the reactor per se is avoided if the catalyst is virtually completely retained in the upper part of the reactor by means of superfine filtration.

摘要： Process and apparatus for preparing 1,2-Dichloroethane by direct chlorination If in the reaction of ethylene with chlorine to form 1,2-dichloroethane (EDC) the catalyst components sodium chloride and iron(III) chloride are used in a molar ratio of below 0.5, then the EDC is obtained in sufficiently high purity to allow direct conversion to vinyl chloride. With maintenance of the stated molar ratio the reaction can be carried out very advantageously in terms of equipment and energy consumption, for example by vaporizing some of the EDC in an expansion vessel.

摘要： In the preparation of vinyl chloride by thermal cracking of 1,2-dichloroethane, three distillation stages are used to distill off first hydrogen chloride, then vinyl chloride and finally entrained hydrogen chloride with vinyl chloride. If, in the last stage, entrained water is not drawn off via the bottom, it is recirculated with the top product to the first stage and causes corrosion. Removal of the water at the top of the third distillation stage, advantageously by drying, prevents the corrosion.
