【摘要】 研究了溴化1,4/1,6-双-α-烷基吡啶丁烷/己烷(GPS)双子表面活性剂与普通阴离子表面活性剂十二烷基苯磺酸钠(SDBS)之间的协同效应,考察了二者复配比例对体系表面张力和临界胶束浓度的影响.实验结果证明,GPS双子表面活性剂与SDBS之间有强的相互作用;当GPS与SDBS的比例为3∶7时,二者的协调效应最强;连接基对协同效应的影响比烷基链长度对协同效应的影响更大.更多还原

【Abstract】 The synergic effects between 1,4-Bis(α-alkylpyridinium)butane/hexane Dibromide gemini surfactants(GPS)and sodium dodecyl benzoic sulfate(SDBS)have been studied,the effect of the ratio of GPS/SDBS on the surface tension and critical micellar concentration(cmc)of the mixture have been investigated.The results show that there are stronger interactions between GPS and SDBS,the strongest synergic effect appeared at a ratio of 3∶7 between GPS and SDBS,and it seems that the spacer affects more the synergic effect than the length of alkyl chain in the gemini surfactants.更多还原
