Abstract

Water-insoluble anion-exchange resins are prepared by condensing (1) a benzene-insoluble vinyl-aromatic polymer cross-linked with up to 30% (calculated on the monomer) of a polyethylenically unsaturated cross-linking agent with (2) a N-(halogenoalkyl)-imide in the presence of a swelling agent and a Friedel-Crafts catalyst, and then saponifying. Copolymers of styrene, substituted styrenes, and vinyl naphthalene with divinyl benzene toluene, ethyl benzene, and vinylether, and trivinyl benzene, ethylene glycol dimethacrylate or diacrylate, dialkyl maleate, or a polyester of e.g. ethylene glycol and maleic acid, which may have a gel or sponge structure are used with for example N-chloromethyl succinimide, phthalimide, a diglycolic acidimide, and N-bromomethyl phthalimide. Friedel-Crafts catalysts mentioned are, stearic chloride, zinc bromide and chloride, and aluminium chloride and concentrated sulphuric acid, and the swelling agents may be ethylene dichloride or dibromide, methylene chloride, carbon tetrachloride, tetrachorethane, trichloro- or tribromoethylene, 1, 1, 2-trichlorethane, pentachloroethane, dichloro-, trichloro, tetrachloro- and pentachloropropanes and 1, 2, 3, 3-tetrachloropropylene. The reaction takes place at elevated temperatures and the imidoalkyl intermediate is separated and saponified by alkaline or acid hydrolysis or by conversion with hydrazine and subsequent acid hydrolysis. The products after isolation and purification are alkylated, with for example alkyl halides, dialkyl sulphates, alkylene oxides, halohydrins, polyhalogen compounds, or epihalohydrins, or a mixture of formaldehyde and formic acid. Secondary, tertiary or quaternary amino derivatives or mixtures thereof may be obtained. Examples describe the reaction of pearl copolymers of styrene, divinyl benzene and ethyl styrene with N-(chloromethyl)-phthalimide, chloromethyl-diglycolic acid imide, N-(chloromethyl)-succinimide and the saponification of the products to yield anion exchange resins. Specifications 654,706, 679,851, 679,852, 700,470, 714,366 and 779,994 are referred to.ALSO:Hydroxy methyl-digylcolic acid imide is prepared by heating diglycolic acid imide in an aqueous formaldehyde solution (40% by vol) and concentrating in vacuum at 40-45 DEG C. The diglycolic acid imide is distilled from diglycolic acid neutralised with ammonia. Specifications 654,706, 679,851, 679,852, 700,470, 714,366 and 779,994 are referred to.
