| 摘 要： | 超临界二氧化碳(ScCO_2)作为一种新兴绿色溶剂是化工学科研究的热点,ScCO2参与构成的两相体系在催化反应中兼具均相和非均相过程的特点,可将反应与分离过程有效结合,即实现"均相反应、非均相分离"的过程强化目的。综述了由ScCO_2参与构成的两相体系(包括ScCO_2-H_2O、ScCO_2-有机液体及ScCO_2-离子液体)在催化反应过程中应用的最新进展,指出了这类体系的研究现状、存在问题和发展趋势,为制备和开发高效清洁的反应和分离介质提供借鉴。

| Abstract: | As a green solvent,supercritical carbon dioxide(ScCO_2) has attracted much more attention due to its unique properties and environmental benignity.The biphasic systems,which were constituted with ScCO_2 phase and a liquid phase,have the especial advantages both of homogeneous and heterogeneous systems,as well as the ability to couple the reaction and separation into only one integrated process easily.Recent applications of the biphasic systems constituted by ScCO_2(including ScCO_2-H_2 O,ScCO_2-organic solv... |
