摘　　要：以异构十三醇聚氧乙烯醚和羟乙基磺酸钠为原料,制备了异构十三醇聚氧乙烯醚磺酸钠(C_(13)EnSO,n=4、6),并对其表面张力、界面张力、润湿性能、泡沫和乳化进行了研究。结果表明:C_(13)E_(4)SO和C_(13)E_(6)SO临界胶束浓度(critical micelle concentration,CMC)无显著差异,C_(13)E_(4)SO在CMC时的表面张力低于C_(13)E_(6)SO;C_(13)E_(4)SO水溶液与C12烷之间界面张力低于C_(13)E_(6)SO;C_(13)E_(4)SO润湿时间短于C_(13)E_(6)SO;两者泡沫和润湿无显著差异。Sodium iso-tridecanol polyoxyethylene ether sulfonates(C_(13)EnSO,n=4 and 6)were synthesized using iso-tridecanol polyoxyethylene ether and sodium isethionate as raw material.The surface tension,interfacial tension(IFT),wetting,foam and emulsification of C_(13)EnSO were tested.The results were as follow:there was no significant difference on the critical micelle concentration(CMC)between C_(13)E_(4)SO and C_(13)E_(6)SO,and surface tension of C_(13)E_(4)SO at CMC was lower than that of C_(13)E_(6)SO.IFT between C_(13)E_(4)SO and dodecane was lower than that of C_(13)E_(6)SO;wetting time of C_(13)E_(4)SO was shorter than that of C_(13)E_(6)SO;there was no significant difference on the foam volume and emulsification between C_(13)E_(4)SO and C_(13)E_(6)SO.
