Abstract: An apparatus for producing ethylenically unsaturated aliphatic halogenic hydrocarbons by thermal cleavage of saturated aliphatic halogenic carbons using an apparatus that introduces an educt gas stream into a reactor which includes at least one supply conduit which opens into the reactor, the supply conduit feeds a heated gas formed from cleavage promotors and radicals produced by a nonthermal plasma device which permits an increased in the yield of the cleavage reaction.

Abstract: 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.

Abstract: The invention relates to a method for producing ethylenically unsaturated aliphatic halogenic hydrocarbons by the thermal cleavage of saturated aliphatic halogenic hydrocarbons. According to said method, an educt gas stream is introduced into a reactor, which comprises at least one supply conduit that opens into said reactor. The supply conduit feeds a heated gas formed from cleavage promoters and radicals into the reactor. The method permits an increase in the yield of the cleavage reaction.

Abstract: A process and an apparatus are described for the preparation of 1,2-dichloroethane by reacting ethene with hydrogen chloride and an oxygen-containing gas in an oxychlorination reactor by means of a fluidised bed with formation of a reaction gas, wherein the reactor gas is filtered outside the oxychlorination reactor by means of at least one filter candle.

Abstract: A process is described for the preparation of 1,2-dichloroethane by reacting ethene with hydrogen chloride and an oxygen-containing gas in an oxychlorination reactor with formation of a reaction gas, wherein the reaction gas is, after filtration, condensed without prior quenching.

Abstract: 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.
