Abstract: Adiponitrile is purified by cooling the liquid or heating the solid so as to produce a suspension of adiponitrile crystals in liquid adiponitrile at a temperature of below 2.0 DEG C., separating the crystals, e.g. on a filter press, vacuum filter, pressure filter or in a centrifuge, washing the crystals, e.g. with pure liquid adiponitrile or with water or an organic liquid, and returning the separated liquid adiponitrile, with or without the wash liquid, to the first or another crystallization zone. The wash liquid may be pure adiponitrile obtained by partly melting the separated solid adiponitrile, e.g. while still in the separation apparatus.

Abstract: Quaternary 2-chloroethylammonium salts of the general formula in which R denotes an alkyl radical having 1 to 3 carbon atoms, R1 denotes a hydrogen atom and X denotes an anion, are prepared by reacting an aqueous or water-containing solution of a corresponding quaternary 2-hydroxyethylammonium salt with hydrogen chloride at a temperature of more than 100 DEG C. and at a pressure of more than 3 atmospheres gauge. Examples describe the preparation of chlorocholine chloride-(trimethyl-(2-chloroethyl)-ammonium chloride).
