一、引言近十几年来化学家们详尽地研究了胶束体系对某些基态有机化学反应速率的影响,发现胶束能显著地提高反应速率,并把这一效应归结为两点:1.胶束能把反应物包围起来,从而增加了反应物的区域浓度,加快了反应速率;2.胶束-水的界面具有一些特殊的性质,例如,离子型胶束表面的区域电场可高达10~6V/cm,这就能大大地影响反应的过渡态,从而影响反应速率。
I. INTRODUCTION In recent decades, chemists have studied in detail the influence of micellar system on the rate of some organic reactions in ground state. They found that micelles can significantly increase the reaction rate and attributed this effect to two points: 1. Micelles can surround the reactants, thereby increasing the concentration of reactants in the region, speed up the reaction rate; 2. Micelle - water interface has some special properties, for example, ionic micelles on the surface of the electric field can be as high as 10 ~ 6V / cm, which can greatly affect the reaction of the transition state, thus affecting the reaction rate.
