Abstract: A method of producing vinyl chloride, pyrolyzing gaseous and liqud hydrocarbons in a plasma jet of hydrogen or in a mixture of hydrogen and methane, with the addition of chlorine and/or HCl gas in such an amount that the content of HCl gas in the pyrolysis gas thus formed should be equal to the content of acetylene therein. Further the pyrolysis gas containing acetylene and ethylene is quenched with liquid hydrocarbons, purified from higher unsaturated hydrocarbons containing 3 or more carbon atoms, the acetylene is reacted with HCl gas, the resulting vinyl chloride is separated, the ethylene is reacted with chlorine, the dichloroethane thus formed is pyrolyzed with the formation of vinyl chloride and HCl gas, the vinyl chloride is separated, and the HCl gas is recycled to the stage of reacting acetylene and HCl gas.Said method makes it possible to increase the total yield of acetylene and ethylene at the stage of pyrolysis up to 85%, and the yield of vinyl chloride up to 82% of the initial hydrocarbons used.

Abstract: The method of preparing esters of glycerol and polyglycerols with monocarboxylic fatty acids having from 5 to 9 carbon atoms consists in that glycerol and polyglycerols are reacted with monocarboxylic fatty acids, having from 5 to 9 carbon atoms at a temperature of 140.degree.-210.degree. C with continuous distillation of water that is present in the reaction zone. Glycerol and polyglycerols are introduced into the reaction as part of still bottoms of the process of distillation of synthetic glycerol obtained by the chlorine method, and containing sodium hydroxide and sodium chloride. The resultant reaction mixture contains the end product, which is isolated by any known method.
