Abstract
The effect of addition of sodium anthranilate to 5 mM micellar solutions of gemini surfactant 1,4-bis(-hexadecyl-,-dimethylammonium)butane dibromide is investigated by H NMR. The solubilization site of anthranilate anion near the micellar surface is inferred. In the micelles, the An ions intercalate among the surfactant headgroups producing morphological changes.
摘要
通过核磁共振氢谱研究了向5 mM双子表面活性剂1,4-双（十六烷基二甲基铵）丁烷二溴化物胶束溶液中添加邻氨基苯甲酸钠的效果。推断出邻氨基苯甲酸根阴离子在胶束表面附近的增溶位置。在胶束中，An离子插入表面活性剂头基之间，产生形态变化。
