摘要: 以十二醇、顺丁烯二酸酐及月桂酸单乙醇酰胺为原料,合成了一种不对称型磺基琥珀酸双酯盐双子表面活性剂。通过单因素试验法优化了双酯化反应条件,其较佳反应条件为:n(十二醇马来酸单酯)∶n(月桂酸单乙醇酰胺)=1∶1,反应温度为140 ℃,反应时间为6 h。通过傅里叶红外光谱、核磁共振对所得表面活性剂的结构进行了表征,并对其表面张力、泡沫性能、乳化力等进行了测定。结果表明:该双子表面活性剂的临界胶束浓度(cmc)为2.21×10-5 mol/L,γcmc为31.1 mN/m;乳化分水时间为278 s,起泡性和稳泡性良好。

Abstract: Lauryl alcohol,maleic anhydride and lauric acid monoethanolamide were used as starting materials to synthesized asymmetric Gemini sulfosuccinate surfactant.The optimized conditions for diesterification are as following:reaction temperature,140 ℃;reaction time,6 h;and n(lauryl alcohol maleic acid monoester)∶n(lauric acid monoethanolamide)=1∶1.The structure of the target compound was characterized by FTIR and 1HNMR.The surface tension,foaming performance and emulsifying power of the product were measured.Results showed that the product has low cmc as 2.21×10-5 mol/L and γcmc as 31.1 mN/m.It displays stronger foaming power and better foam stability.Water separation time of the emulsion made of the product achieves 278 s.

Key words: Gemini surfactant, succinic acid diester, asymmetry
