| 摘 要： | 以环氧氯丙烷(EPIC)和三甲胺(TMA)为原料,碘化钾为催化剂,在乙醇介质中常温下合成了高活性醚化剂2,3-环氧丙基三甲基氯化铵(GTA)。采用正交实验法考察了反应温度、物料配比、催化剂用量和反应时间对产品收率的影响。GTA最佳合成工艺条件为:n(EPIC)∶n(TMA)∶n(KI)=1∶0.3∶0.02,反应温度20℃,总反应时间4 h,在此优化条件下收率可达87.1%。

| Abstract: | 2,3-Epoxypropyl trimethyl ammonium chloride(GTA) is synthesized at normal temperature using epichlorohydrin and trimethylamine as raw materials and potassium iodide as catalyst in the presence of ethanol.Various factors influencing the yield are investigated by orthogonal experiments.The optimal reaction conditions are obtained as total reaction time.The yield of 2,3-epoxypropyl trimethyl ammonium chloride can be up to 87.1% under such conditions. |
