| 摘 要： | 以环氧氯丙烷(ECH)和三甲胺(TMA)为原料,在40 kHz超声辅助下合成了季铵盐型活性醚化剂环氧氯丙基三甲基氯化铵(GTA);GTA在超声辅助下与硬脂酸反应,合成了阳离子单酯表面活性剂N,N,N-三甲基-2-羟基-3-硬脂酰氧基丙基氯化铵(CMESA)。通过元素分析,IR等手段对CMESA进行了表征,并考察了反应温度,n(GTA)∶n(硬脂酸),pH和反应时间等因素对产率的影响。结果表明,CMESA的合适合成条件为:超声频率50 kHz,n(GTA)∶n(硬脂酸)=3∶1,反应温度70℃,反应时间4 h,此条件下CMESA的产率为94.90%。

| Abstract: | Quaternary salt type active etherification agent epoxychloropropyltrimethylammonium chloride(GTA) was synthesized by epichlorohydrin(ECH) and trimethylamine(TMA) under help of 40 kHz ultrasonic wave.A cationic monoester surfactant N,N,N-trimethyl-2-hydroxy-3-stearoyloxy-propylammonium chloride(CMESA) was synthesized by reaction of GTA and stearic acid under help of ultrasonic wave.The product was characterized by elemental analysis,IR,et al.Effects of reaction temperature,mole ratio n(GTA)∶n(stearic acid),pH and reaction time on yield of product were studied.The results showed that the suitable conditions for synthesis of CMESA were:ultrasound frequency 50 kHz,n(GTA)∶n(stearic acid)=3∶1,reaction temperature 70 ℃,reaction time 4 h.Under these conditions,yield of CMESA achieves 94.90%. |
