Abstract: A process for the thermal dissociation of an organic substance containing chlorine in which substantially anhydrous hydrogen chloride is obtained. The substance containing chlorine is introduced in a first stage into a salt melt in the absence of oxygen, hydrogen chloride is discharged from the reaction mixture and then oxygen is supplied to the salt melt in a second stage.

Abstract: 1454028 Vinyl chloride BASF AG 14 Feb 1974 [15 Feb 1973] 6676/74 Heading C2C Vinyl chloride is produced by cleavage of dichloroethane to form a product mixture of vinyl chloride and HCl together with unreacted dichloroethane and unsaturated impurities, removal of the HCl formed, and adding 0À01-1 wt. per cent of Cl 2 (based on the dichloroethane originally used) to the reaction mixture after the cleavage reaction to react with unsaturated impurities and subsequently recovering the vinyl chloride by separation from the dichloroethane and chlorinated impurities. The Cl 2 is preferably dissolved in some of the unreacted ClCH 2 CH 2 Cl after separation from the vinyl chloride and the resulting mixture is added to the reaction mixture after removal of HCl. Alternatively Cl 2 may be added prior to the removal of HCl. The reaction with Cl 2 may be performed at 20 to 100 C. using 0À1-0À6 wt. per cent Cl 2 , in order to react with butadiene, chloroprene and monovinylacetylene impurities in the vinyl chloride.

Abstract: O.Z. 0050/034805 A supported catalyst containing copper and alkali metals, wherein the content of copper is from 1.0 to 12% by weight, based on total catalyst and expressed as metal, and the total content of the alkali metals potassium, lithium and sodium is from 0.3 to 9% by weight, based on total catalyst. The novel catalyst is useful for the preparation of 1,2-dichloroethane by oxychlorination of ethylene.
