摘　　要：对 3 -氯 -2 -羟丙基三甲基氯化铵 (简称 CTA)的新法研制过程进行了较详细研究 .利用对比因素实验对反应的条件进行了探索 ,并得到了最佳工艺条件 :三甲胺与 1 ,3 -二氯丙醇的配比为 1∶ 1 .1 0～ 1 .68;反应温度控制在 55～ 80℃ ,反应时间≥ 6h;对合成的CTA产品借助于 IR谱、MS谱和高效液相色谱等手段进行了分析 ,结果表明为目标产品 ,产品纯度为 98% .The investigation about the new method of preparing of 3-chloro-2 -hydroxypropyl tri-methyl ammonium chloride, for short CTA, was studied. By using the balance factor experiment, the condition of the synthesize reaction were explored. The optimum process was gained at last. The optimum process are as follows: the ratio of 1,2-dichloro-propyl alcohol and tri-methyl ammonium is 1∶1.10～1.68; the temperature of the reaction are 55～80 ℃; the time of the reaction is≥6 hours. And the CTA products were determined by means of IR, MS and HPLC. Analysis result proves: the end product is just about aim products its purity is 98%.
