Synthesis and chromatographic properties of new polymer-based anion exchangers

Abstract

New anion-exchangers with functional groups of trimethylammonium were obtained as a result of the synthesis, which involves acetylation of styrene-divinylbenzene copolymer (25% of divinylbenzene), reductive amination of carbonyl groups and following methylation. Two methods of reductive amination were studied and optimal conditions for these reactions were chosen. Chromatographic properties of anion exchangers were studied by means of suppressed ion chromatography with conductometric detection. The obtained anion exchangers demonstrate high selectivity, maximal efficiency is 30000 theoretical plates.
