摘要

测定了糖基双子阳离子表面活性剂(SGCS)与十二烷基硫酸钠(K_(12))复配体系的稳定性和表面性能。由实验结果可知,在宽的复配范围内不同碳链长度的SGCS与K_(12)均有良好的复配稳定性;C_(14)-SGCS/K_(12)复配体系表现出明显的协同增效作用,当n(C_(14)-SGCS)∶n(K_(12))为3∶5时复配溶液临界胶束浓度(cmc)、cmc时的表面张力(γ_(cmc))和降低表面张力的效率(pc_(20))分别为1.1×10~(-5) mol/L、23.69 mN/m和5.48,均明显优于C_(14)-SGCS和K_(12)自身的表面性能。
        The stability and surface activity of the blends of sugar-based cationic Gemini surfactants(SGCS)and sodium dodecyl sulfate(K_(12))were studied.The results show that the blend systems being composed of K_(12) and SGCS with different chain length have exhibited good stability in a wide rang of molar ratios of SGCS/K_(12).For the mixture of C_(14)-SGCS/K_(12),an obvious synergistic effect has been observed.The critical micelle concentration(cmc),surface tension at cmc(γ_(cmc))and the efficiency of reducing surface tension(pc_(20))of the mixture of n(C_(14)-SGCS)∶n(K_(12))=3∶5 are 1.1×10~(-5) mol/L,23.69 mN/m and 5.48,respectively,which are obviously superior to the performance of individual C_(14)-SGCS or K_(12).
