CATALYST FOR WATER-ALKALINE DEHYDROCHLORINATION OF POLYCHLOROALKANES Russian patent published in 1994 - IPC

FIELD: chemical engineering. SUBSTANCE: catalyst is reaction product received by mixing for 1 - 2 h nonaqueous and aqueous solution of tertiary amine, haloalkyl, alcohol and polychloralkane in the 1:1:(2-3):(2-4) molar ratio with the process proceeding at the temperature ranging from 40 to 90 C. The amine used as tertiary one has the formula R₁ R₂R₃N. R₁, R₂, R₃ alkyl, C₁-C₅-alkyl, γ- chlorallyl, benzyl, unsaturated C₄-C₅-hydrocarbons. The haloalkyl selected belongs to allyl or benzyl type. The alcohol has an unsaturated or aromatic group in β-position relative to the atom of oxygen. EFFECT: higher quality of catalyst. 2 tbl
