Abstract: Immobilized ionic liquids can overcome the shortages of common ionic liquid,such as low mass transfer ability,and can decrease the usage amount of ionic liquids.In this paper,the preparation of immobilized ionic liquid catalyst in recent years is reviewed and the modification and effect mechanism of immobilized ionic liquid upon the characters and performances of the catalyst in the catalysis reactions are analyzed.The perspective potential of immobilized ionic liquids catalyst is described.
