摘要
本文采用高分辨核磁共振方法，考察了苯甲醇在三种类型表面活性剂胶束中的增溶作用。实验发现，无论是在两性表面活性剂Ｃ１２ＢＥ，还是在阴离子表面活性剂ＳＤＳ和阳离子表面活性剂ＤＴＡＢ胶束中，苯甲醇均增溶在胶束与水的界面层和胶束栅栏层。由此对其在三种胶束中的增溶量大小作出合理解释。
he solubilization of benzyl alcohol in three kinds of surfactants that have the same hydrocarbon chain but different kinds of headgroups has been invetigated by the high resolution proton nuclear magnetic resonance spectroscopy (1HNMR).It has been found that the solubilizated locations in the Zwitterionic surfactant C_12BE、anionic surfactant SDS and cationic surfactant DTAB are all the palisade layer.The solubilization amount for benyl alcohol appears as follows:DTAB>SDS>C_12BE as ascending concentration of surfactants.
