摘要
介绍了吸附胶团的结构特点、影响吸附胶团催化的一些因素和在固体表面上的固定化表面活性剂体系的催化作用。吸附胶团是表面活性剂在固 液界面形成的缔合结构 ,它可以是吸附单层、双层、半球形、球形等。吸附胶团和利用表面接枝等技术在固体表面形成的不溶性表面活性剂体系 ,在一定条件下 ,可对某些反应起催化作用 ,有利于提高反应产率并使反应产物分离变得容易 。
In this paper, structure features of admicelles, some factors affecting admicellar catalysis and catalysis of surfactant systems immobilized on the surface of solids are introduced. Admicelles are the associated structures of surfactants formed on the solid/liquid surface, which can be adsorption monolayer, bilayer, hemisphere or sphere, etc. Adimcelles and insoluble surfactant systems can be formed on the solid surface by surface grafting technology, they have catalytic effect on some chemical reactions under certain conditions. It helps to increase the reaction rate and make the separation of reaction products easier, which will make the application of micellar catalysis to be possible.
