摘要： 目前离子液体的成本高、粘度大限制了离子液体的工业应用. 固定化离子液体是将离子液体填充入多孔有机或无机载体的空隙形成的液体膜，固定化过程可以通过物理吸附、包埋或通过化学键合的方法实现. 将离子液体固定化可以增大离子液体的比表面积，从而提高离子液体的利用效率和稳定性. 固定的离子液体宏观呈固相，更有利于回收. 本工作介绍了离子液体的固定化方法以及固定化离子液体在催化、分离方面的应用进展.

Abstract: The high cost and unendurable viscosity of ionic liquids restrict the industrial application. Immobilization of ionic liquids is the process of filling the pores of supported materials with ionic liquids. Immobilization can be performed by physical adsorption or chemical bonding through ionic liquids and the surface of supporting materials. The immobilization of ionic liquids enlarges the surface area of ionic liquids, thus their utilization efficiency and stability can be improved. Immobilized ionic liquids are in solid phase, thus they are easily recovered. The methods for immobilization and the applications of immobilized ionic liquids in catalysis and separation processes are reviewed in this paper.
