METHOD OF PRODUCTION OF VINYLIDENE CHLORIDE Russian patent published in 2007 - IPC C07C17/25 C07C21/08 B01J31/02 C25B3/00 

FIELD: chemical industry; methods of production of vinylidene chloride.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the method of production of vinylidene chloride by the dehydrochlorination of 1,1,2- trichloroethane with formation of the target product and the quaternary ammonium salts. As the reactant of the dehydrochlorination they use the water-alcoholic solutions of hydroxides - dimethyl-β or γ- chlorodipropenyl of ammonium gained by the electrolysis of the solutions of dimethyl-β or γ- chlorodipropenyl of ammonium chloride in the water at presence of methyl, ethyl or butyl alcohols in the electrolyzers with the ion-exchange membranes. At that the gained hydroxides are sent to the dehydrochlorination. The technical result of the invention is creation of the waste-free, highly-efficient and pollution-free process of production of vinylidene chloride.

EFFECT: the invention ensures creation of the waste-free, highly-efficient and pollution-free process of production of vinylidene chloride.
