摘要
A method of purifying 3-chloro-2-hydroxypropyl trialkylammonium chloride. An aqueous slurry is prepared containing about 70-98 wt. % total solids including the chloride and impurities associated with the preparation thereof. To this slurry is then added a miscible alcohol having about 3-4 carbon atoms. A solid filtrate is collected and optionally washed with additional alcohol and dried. The solid filtrate is substantially more pure in the chloride than the starting material.
