Abstract: The process according to the invention comprises reacting the residues at temperatures of above 2000 DEG C and pressures of 1 to 100 bar with a gas mixture promoting combustion in a combustion chamber equipped with cooling devices. The gaseous reaction products which, upon leaving the combustion chamber, have temperatures of 200 to 800 DEG C are first cooled in a first cooling zone a) to temperatures in the range from 80 DEG C to 10 DEG C. The gaseous top products are treated in a process step b) in a suitable device with concentrated hydrochloric acid in the form of droplets having an average diameter of less than 500 mu .

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: Process for the preparation of 1,2-dichloroethane by reacting ethylene, hydrogen chloride and oxygen in the presence of a supported catalyst, in the form of a solid bed, in only one reaction zone, separating 1,2-dichloroethane and water from the gas mixture leaving the reaction zone, and recycling the waste gas, which contains up to 20% by volume of ethylene, to the reaction zone, fresh ethylene, hydrogen chloride and oxygen being added to the waste gas.

Abstract: 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.
