摘　　要：合成了己酯和辛酯系列单链磺基琥珀酸酯钠盐(SS)及双子磺基琥珀酸酯钠盐(GSS)表面活性剂,主要研究了SS与GSS的渗透性、乳化性、耐硬水性及临界胶束浓度随疏水链支化度的变化规律,并进行比较。结果表明:己酯系列SS与GSS的乳化性、耐硬水性和渗透性随疏水链支化度的变化规律相同;当GSS连接基的长度小于亲水基平衡距离时,己酯系列GSS与SS的临界胶束浓度随疏水链支化度变化规律相同,反之则变化规律相反;随着疏水链支化度的改变,辛酯系列SS与GSS的耐硬水性和临界胶束浓度的变化规律相同,渗透性变化规律相反,乳化性变化规律不同。A series of sodium hexyl and octyl succinic acid ester sulfonate（ SS） and a series of sodium bis-hexyl and bis- octyl Gemini succinic acid ester sulfonate（ GSS） were synthesized. The relationship between the performances,such as permeability,emulsification,resistance to hard water and the critical micelle concentration,and the branching degree of the hydrophobic chain were mainly investigated. Results showed that,for the series of hexyl SS and hexyl GSS,the changing tendency of the emulsification and the resistance to hard water are same as the change of branching degree of the hydrophobic chain. When the spacer length is less than the equilibrium separation of the hydrophilic groups,trends of change of the critical micelle concentration of the hexyl GSS and the SS are same with the branching degree of the hydrophobic chain,and when the spacer length is longer than the equilibrium separation,the changing tendency is on the contrary. As the change of the branching degree of the hydrophobic chain of the octyl SS and octyl GSS,change of the resistance to hard water and the critical micelle concentration is in same direction,while the permeability changes contrarily. The emulsification changes differently.
