反胶团在超临界二氧化碳体系中的研究进展

超临界二氧化碳是一种环境友好型溶剂，它作为有机溶剂的替代品已成功的应用于绿色化学过程的开发。但超临界二氧化碳对极性物质的溶解度小，甚至不能溶解，反胶团的引入为这一问题的解决提供了新的手段。本文阐述了超临界二氧化碳反胶团的基本原理，研究了表面活性剂的选择和设计，讨论了反胶团对水的溶解能力、助表面活性剂以及压力对超临界二氧化碳反胶团性质的影响，最后总结了超临界二氧化碳反胶团在萃取、有机反应及纳米微粒合成等领域的应用。

Research Progress of Reverse Micelles in Supercritical Carbon Dioxide

Supercritical carbon dioxide can be used as an environmentally benign solvent replaced for organic solvent, which successfully enable the development of the green chemical process. A general disadvantage of ScCO 2, however, is that it is very poor solvent for polar molecules. It is a new method to enhance its solubility by leading reverse micelles into ScCO 2 In the paper, the principle of reverse micelles in ScCO 2 is interpreted, the select and design of surfactants are researched, the effect of W 0, cosurfacent and pressure on the properties of reverse micelles in ScCO 2are discussed, at last, the applications of reserve micelle in ScCO 2 in extraction, organic reaction and the preparation of nanoparticals are summarized
