Abstract: A process for the manufacture of 1,2-dichloroethane from ethylene by reaction with hydrogen chloride and inert gases containing oxygen, and also by reaction with chlorine, is described. The two chlorination reactions are carried out successively at 180 DEG to 360 DEG C. and under a pressure of 0.09 to 1.1 MPa in a common reaction space containing fluidized catalyst particles. A stoichiometric excess of ethylene is employed for the first chlorination reaction. The heat formed in the reaction space is removed by indirect cooling. The process is simple in terms of apparatus and permits a better re-use of the total heat of reaction of the chlorination of ethylene.

Abstract: Vinyl chloride is produced by pyrolytic decomposition of 1,2-dichloroethane in a furnace with coiled up reaction tube having an internal diameter of from 12 to 16 cm. The dichloroethane is vaporized completely in the convection zone of the pyrolytic furnace, different amounts of heat are supplied to the different zones of the reaction tube and, after decomposition in the working up of the reaction products, the low-boiling constitutents are treated with chlorine and separated together with the high-boiling constituents.

Abstract: The activity of supported silver catalysts used up in the direct oxidation of ethylene with molecular oxygen or air is improved by impregnating the catalyst arranged in a fixed bed with a solution of a caesium and/or rubidium compound in an inert organic solvent, optionally together with up to 40% by weight of water, calculated on the total liquid, as dissolving intermediary, so as to produce a concentration gradient of from 0.3 to 20 parts of caesium and/or rubidium per 1 million parts of catalyst and per meter of fixed bed, counter to the direction of flow of the gas to be reacted. In this manner the activity of the catalyst is considerably improved which results in an increased selectivity of the oxidation of ethylene to ethylene oxide.
