摘要
以硬脂醇、金属钠及3-氯-2-羟基丙基三甲基氯化铵为原料合成了3-烷氧基-2-羟基丙基三甲基氯化铵(OPAC),进一步与硬脂酰氯反应后得到醚-酯型双长链季铵盐阳离子表面活性剂3-烷氧基-2-酰氧基丙基三甲基氯化铵。正交实验确定的最佳合成条件为:1,4-二氧六环为溶剂,用量40mL,n(OPAC)∶n(硬脂酰氯)∶n(吡啶)=1∶1∶1,回流加热反应5h,收率为93.0%。产物结构通过红外及核磁共振氢谱表征。产物表面活性较高,具备良好的织物柔软性及酸碱稳定性。
3-Alkoxy-2-hydroxypropyl trimethyl ammonium chloride（OPAC）was synthesized by stearyl alcohol,metal sodium and 3-chloro-2-hydroxypropyl trimethyl ammonium chloride.Double long chain ether-ester quaternary ammonium salt cationic surfactants 3-alkoxy-2-acyloxy trimethyl ammonium chloride was further synthesized with OPAC and stearyl chloride.Through orthogonally arranged experiments,the optimal esterification conditions were obtained as follows：40mL 1,4-dioxane was used as solvent,n（OPAC）∶n（stearyl chloride）∶n（pyridine）=1∶1∶1and refluxing time was 5h.The yield of end product was 93.0%.The structure was confirmed by IR and 1 H NMR.Performance results show that the product has high surface activity,good fabric softness and pH stability.
