摘　　要：双烷基二苯醚双磺酸盐是一种性能优异的双子表面活性剂,被广泛应用于日化、材料、印染等领域。为了进一步研究磺酸盐类表面活性剂结构与性能的关系,测定了单/双烷基二苯醚双磺酸钠(C_(12)-MADS/C_(12)-DADS)的胶束化热力学、润湿、泡沫和乳化性能,并与十二烷基苯磺酸钠(C_(12)-LAS)进行对比分析。结果表明,不同温度下的临界胶束浓度(cmc):C_(12)-DADS(1.49×10^(-4)~1.63×10^(-4)mol/L)<C_(12)-MADS(3.40×10^(-4)~4.00×10^(-4)mol/L)<C_(12)-LAS(1.80×10^(-3)~2.40×10^(-3)mol/L)。C_(12)-DADS的润湿性能优于C_(12)-MADS。此外,C_(12)-DADS具有较低的起泡能力和乳化能力。The di-dodecyl diphenyl ether was a Gemini surfactant with excellent properties.It was widely used in various fields such as daily chemicals,materials,printing and dyeing.In order to further study the relationship between structure and properties of sulfonate surfactants,the themodynamic properties of micellization,wetting,foam and emulsifying properties of mono-and di-dodecyl diphenyl ether disulfonate(C12-MADS/C12-DADS)were investigated,and then the di-dodecyl diphenyl ether and alkylbenzene sulfonate(C12-LAS)were compared and analyzed.The results showed that the critical micelle concentration at different temperatures was C12-DADS(1.49×10^-4~1.63×10^-4 mol/L)<C12-MADS(3.40×10^-4~4.00×10^-4 mol/L)<C12-LAS(1.80×10^-3~2.40×10^-3 mol/L).The wettability of C12-DADS was better than that of C12-MADS.In addition,C12-DADS possessed a lower foam ability and emulsifying ability than that of C12-MADS and C12-LAS.
