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.

Method for producing unsaturated halogenic hydrocarbons and device suitable for use with said method

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.

Method for producing 1, 2-dichloroethane by direct chlorination

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.
