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.
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.
