Progress in Phase Equilibrium Studies of Mixtures Containing Ionic Liquid

室温离子液体混合物的相平衡数据是设计和优化涉及离子液体的化学反应与分离工程的重要基础。本文综述了近年来室温离子液体混合物,特别是室温离子液体+有机物体系的气-液平衡、液-液平衡和固-液平衡的研究进展,总结了这些混合物相行为的基本热力学规律以及对萃取分离工程的指导作用。

The data of phase equilibria for mixtures containing room temperature ionic liquid is important basis for the design and optimization of chemical reactions and separation processes involving ionic liquids. In this paper, the recent progress in the studies of vapor-liquid, liquid-liquid and liquid-solid equilibria is reviewed for ionic liquid ＋ organic molecular solvent systems. The basic thermodynamic regularity for phase behavior of such mixtures and its applications in extraction and separation processes are highlighted.
