摘要: 研究了1,3-丙二醇双子琥珀酸二异辛酯磺酸钠(GSS362)和辛基酚聚氧乙烯醚(TX-100)复配物在水中的表面性质和胶束化行为,并对理想混合临界胶束浓度以及混合体系中各组分在表面吸附层和胶束中的组成、相互作用参数和热力学参数进行分析计算。结果表明,复配物在水溶液中不存在协同效应,但是TX-100的加入明显降低了GSS362的临界胶束浓度,混合胶束的形成为自发过程,胶束中GSS362与TX-100分子具有较弱的相互作用,胶束中富含非离子表面活性剂TX-100。

Abstract: The surface properties and micellization behavior of blend of 1,3-propanediol Gemini sodium bis-isooctyl succinyl ester sulfonate (GSS362) and octylphenol ethoxylate (TX-100) in aqueous solution were investigated.The cmc of ideal mixed surfactants and the composition as well as the interaction parameters and thermodynamic parameters of separate components in the surface adsorption layer as well as in the micelles were also examined and calculated.Results showed that:no synergistic effect of the blend surfactants is found in the aqueous solution;however,with the addition of TX-100,the cmc of the blend surfactants decreases apparently as comparing to that of GSS362 alone;the formation of mixed micelle is spontaneous and the molecular interaction between GSS362 and TX-100 is weak;TX-100 is enriched in the micelles of the blend surfactants.

Key words: succinyl ester sulfonate, Gemini surfactant, blend, micelle, cmc, interaction parameter
