Abstract: In the present invention there is disclosed a process for preparing 1,2-dichloroethane by reacting ethylene with chlorine in the presence of a catalyst based on sodium chloride and iron(III) chloride, during which process the molar ratio of sodium chloride to iron(III) chloride is maintained below 0.5 all over the reaction. The proposed process is carried out at a temperature ranging from 50 to 105 degC and under positive pressure up to 0.1 MPa. The apparatus for making the above described process comprises a reactor (1) that is interconnected through the mediation of a piping (5) with a decompression tank (6) that is provided with a piping (7) for offtake of evaporated product and a piping (8) for backflow of the non-evaporated product, whereby a piping (11) for backflow of the product partial flow into the reactor (1) is branched from said pining (5).

Abstract: Process and apparatus for preparing 1,2-Dichloroethane by direct chlorinationIf 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.

Abstract: The invention concerns a process for preparing 1,2-dichloroethane (EDC) by feeding chlorine and ethylene into circulated EDC which contains a catalyst. A partial stream of the reaction mixture is fed to a flash vaporization system and the vaporized EDC is separated from its light volatile components which are returned to the reaction.
