ABSTRACT:
The reaction mixture obtained in the production of 2,3-epoxypropyltrialkylammonium chlorides by treatment of chlorohydroxypropyltrialkylammonium chlorides with alkaline acting materials in aqueous medium containing impurities which create problems in the subsequent use of the 2,3-epoxypropyltrialkylammonium chloride. According to the invention the reaction mixture is freed from these impurities by separating it from undissolved impurities by employing at least about 0.2 mole of 2,3-epoxypropyltrialkylammonium chloride per mole of water.
