| Abstract：The synthesis of 3 chloro 2 hydroxypropyl trimethylammonium chloride (CHPTMA) under aqueous process at room temperature was discussed. Trimethylamine hydrochloride (TMAHC) was firstly prepared from trimethylamine (Industrial grade) and hydrochloric acid (w=36%), then epichlorohydrin (EPIC) was dropped in it. The effects of the reaction temperature, drop time of EPIC, total reaction time, pH, catalyst, reaction medium, and molar ratio of EPIC and TMAHC on yield of CHPTMA were studied. |
| Key words：chloro-2-hydroxypropyl trimethyl ammonium chloride; etherification agent; synthesis; aqueous process |
