METHOD FOR PREPARING VINYL CHLORIDE Russian patent published in 2007 - IPC C07C17/25 C07C21/06 B01J31/02 C25B3/00

Abstract RU 2292328 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of vinyl chloride by the liquid-phase dehydrochlorination process of 1,2-dichloroethane. As reagent for the liquid-phase dehydrochlorination process of 1,2-dichloroethane the method involves using alcoholic solutions of quaternary ammonium salts of the general formula: [R₁-R₂-R₃-R₄N]⁺OR^- wherein R₁-R₂-R₃ mean (C₁-C₄)-alkyl; R₃-R₄ mean propenyl, β- or γ-chloropropenyl; R means (C₁-C₄)-alkyl, benzyl synthesized by electrolysis of corresponding quaternary ammonium salts in electrolyzers with ion-exchange membranes. Invention provides the development of wasteless, highly efficient, ecologically pure technology of synthesis of vinyl chloride and simplifying a method for synthesis of vinyl chloride based on decreasing temperature and pressure in carrying out the process.

EFFECT: improved method of synthesis.
