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 (K12) 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K12均有良好的复配稳定性;C14-SGCS/K12复配体系表现出明显的协同增效作用,当n (C14-SGCS) ∶n (K12) 为3∶5时复配溶液临界胶束浓度 (cmc) 、cmc时的表面张力 (γcmc) 和降低表面张力的效率 (pc20) 分别为1. 1×10 -5 mol/L、23.69 mN/m和5.48,均明显优于C14-SGCS和K12自身的表面性能。

Abstract:

The stability and surface activity of the blends of sugar-based cationic Gemini surfactants (SGCS) and sodium dodecyl sulfate (K12) were studied. The results show that the blend systems being composed of K12 and SGCS with different chain length have exhibited good stability in a wide rang of molar ratios of SGCS/K12. For the mixture of C14-SGCS/K12, an obvious synergistic effect has been observed. The critical micelle concentration (cmc), surface tension at cmc (γcmc) and the efficiency of reducing surface tension (pc20) of the mixture of n(C14-SGCS)∶n(K12)=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 C14-SGCS or K12.

Key words: sugar-based surfactant, Gemini surfactant, cation, surface tension, blend
