Abstract
3-Chloro-2-hydroxypropyltrimethylammonium chloride(CHPTMAC) is widely used as a quaternary ammonium cationic etherifying agent.The quantity needed only for the preparation of cationic starch is very large.There are many processes to prepare CHPTMAC.The most common one is a process entailing reaction of epichlorohydrin with trimethylammonium chloride in aqueous system.But the impurities including by-products from side reactions and remaining reactants will deeply influence the quality of the product.In order to upgrade the quality,the impurity contents must be rigidly controlled.In this paper a review was given to describe the advance in synthesis of CHPTMAC,and the reaction conditions and method of product purification were emphathetically dicussed.
