摘要： 以二聚酸和N-甲基牛磺酸钠为原料,经酰氯化和Schotten-Baumann缩合反应合成了一种磺酸盐型双子表面活性剂,并对其相关性能进行了表征。结果表明,通过正交试验获得的磺酸盐型双子表面活性剂C34H66(CON(CH3)CH2CH2SO3Na)2的优化合成条件为:反应温度15 ℃,反应时间5 h,碱质量分数40%,n(N-甲基牛磺酸钠)∶n(二聚酸酰氯)=2.3∶1。合成的C34H66(CON(CH3)CH2CH2SO3Na)2具有更高的表面活性,其γcmc和cmc分别为30.4 mN·m-1和3.55×10-4 mol·L-1。泡沫性能分析表明其具有良好的起泡性和稳泡性,水溶液的泡沫高度和半衰期分别是传统表面活性剂的1.3～3.2倍和12～33倍。

Abstract: A kind of sulfonate type gemini surfactant was synthesized with dimmer acid and sodium N-methyl-β-amino ethyl sulfonate as starting materials via acylation and Schotten-Baumann condensation;and its relevant properties were characterized.Based upon orthogonal designed experiments,the optimum reaction conditions were obtained as:reaction temperature,15 ℃;reaction time,5 h;mass fraction of NaOH,40%;molar ratio of sodium N-methyl-β-amino ethyl sulfonate to dimmer acyl chloride,2.3∶1.The product displays higher surface activities as compared with the conventional surfactants.Its γcmc and cmc were determined as 30.4 mN·m-1 and 3.55×10-4 mol·L-1,respectively.In addition,its foaming power and foam stability is good,with foam height and foam half life 1.3-3.2 times and 12-33 times as compared with that of the conventional surfactants respectively.

Key words: gemini surfactant, synthesis, surface activity, foam property
