摘　　要：以顺丁烯二酸酐分别与正辛醇、异辛醇、正癸醇和异癸醇在对甲苯磺酸的催化作用下进行酯化反应,然后再与亚硫酸氢钠发生磺化反应,合成出一系列磺基琥珀酸双酯钠盐（SS）表面活性剂SSN8,SSI8,SSN10和SSI10。采用红外光谱对目标产物进行结构表征确定了化合物结构。评价了SS表面活性剂的表面性能和与直链烷烃间的界面性能。结果表明,SS系列表面活性剂的临界胶束浓度在10-6~10-3mol/L数量级,对应的表面张力在24.90~30.00 m N/m;界面性能评价表明,支链磺基琥珀酸双酯钠盐比相应的直链磺基琥珀酸双酯钠盐适合碳数更高的油相。A series of surfactant sodium dialkyl sulfosuccinates,SSN8,SSI8,SSN10 and SSI10 were prepared through two steps. For the first step,cis-butenedioic anhydride reacted with n-octanol,iso-octanol,n-decanol,and iso-decanol separately to obtain diesters. Then,the diesters were sulfonated by sodium bisulfite to produce the sulfosuccinates. The structure of the target products was characterized by FTIR. Surface performance of aqueous solution of the target products as well as interfacial performance between aqueous solution of the target products and normal alkanes was evaluated. The cmc of these surfactants is in the range of10-6-10-3mol / L magnitude. The corresponding surface tensions are in the range of 24. 90-30. 00 m N / m.According to the results of interfacial tension measurement,the sulfosuccinates with branched carbon chain are more suitable for oil phase with higher carbon numbers than the sulfosuccinates with straight carbon chain.
