R12TAB/苯甲醇/水体系混合胶束的微观结构研究

绘制了3-十二烷氧基-2-羟丙基三甲基溴化铵（R12TAB）／苯甲醇／水体系的三元相图，采用。HNMR方法研究了该体系胶束的微观结构，与电导法对照确定了W／O型胶束、O／W型胶束和油水双连续结构存在的区域，通过。HNMR谱图分析了苯甲醇在各胶束中的增溶位置。结果发现：苯甲醇主要增溶在胶束的栅栏层中，极性头靠近胶束界面，但由于不同胶束所处的微环境不同，苯甲醇沿烃链的分布也不相同。

Study of microcosmic structure of mixed micelles in R12TAB/benzyl alcohol/water system

The ternary phase diagram of 3-dodecyloxy-2-hydroxypropyl trimethyl ammonium bromide(R_(12)TAB)/benzyl alcohol/water system was drawn based on experimental data.The microcosmic structure of the micelle were studied by using proton nuclear magnetic resonance spectroscopy(~1HNMR).Three types of regions(W/O micelle,O/W micelle,as well as oil-water double continuous structure regions)were deduced in the R_(12)TAB/benzyl alcohol/water micellar solution by comparing with conductivity measurements.The solubilizing positions of benzyl alcohol in the micelles were deduced according to the~1HNMR spectrum analysis.The results show that the benzyl alcohol is solubilised at the palisade layer and the polar group is absorbed closely to the micellar surface.As the microenvironment of different micelles is different,the distribution of benzyl alcohol along the hydrocarbon chain of the surfactant is not alike.
