中文摘要: 研究了阳离子表面活性剂DTAB与不同助表面活性剂、油相形成的微乳液体系的溶水能力,并考察了温度、pH对微乳液体系稳定性的影响。分别绘制了不同体系的拟三元相图。研究结果表明:当DTAB与正丁醇质量比为13∶7,(DTAB+正丁醇)与环己烷质量比为3∶1时,DTAB/正丁醇/环己烷/水微乳液体系具有较大的稳定区域,其最大溶水量在50%左右。该微乳液体系在温度低于80℃时,稳定区域受温度影响较小;pH对该体系稳定性影响不大。
Abstract:The water solubility of microemulsion system composed of DTAB, different co-surfactant and oil was investigated. The effect of temperature, pH value on the stability of the systems was studied. The pseudo-ternary phase diagrams in quaternary microemulsion systems of DTAB were measured. The results show that when the mass ratio of DTAB to n-butyl alcohol is 13∶7, and the mass ratio of both DTAB and n-butyl alcohol to cyclohexane is 3∶1, the maximum water solubilizing capacity in DTAB/n-butyl alcohol/cyclohexane/water system is 50%. The influence of temperature below 80℃ and pH value on the stability of this system are negligible.
