THE AMINE MODIFIED ACRYLIC COPOLYMERS AS CATALYSTS IN THE REACTION OFOCTYLBROMIDE WITH SODIUM-CYANIDE

Amine-modified and alkylated (with butyl bromide or hexyl bromide) acr ylonitrile-butyl acrylate-divinylbenzene terpolymers and alkyl acrylat e-divinylbenzene copolymers (where alkyl= methyl, ethyl or butyl) were used as catalysts in the reaction of octyl bromide with cyanide anion s. The dependence of catalytic activity as a function of the acrylate content and swelling properties was investigated. The most effective c atalyst was butyl acrylate-divinylbenzene copolymer. This sample showe d maximum toluene uptake from the toluene/water mixture.
