摘要:

概述了不同种类离子液体在催化酯化反应中的应用。采用离子液体催化酯化反应,催化剂热稳定性好、效率高、环境友好且可回收重复利用,克服了传统方法普遍存在的副反应多、催化剂不易回收、设备腐蚀性大、环境污染以及后处理困难等缺点。探索了离子液体催化酯化的反应机理,指出了离子液体新体系发展需要解决的瓶颈问题及其在催化酯化反应中存在的不足,展望了离子液体在催化酯化反应中的发展方向。

Abstract:

Different types of ionic liquids in catalytic esterification reactions are summarized. Traditional catalysts are often troubled by more side reactionshigh corrosivenessenvironmental pollutionseparation difficultyand cannot be recycled. Contrarilyionic liquids show good thermal stabilityhigh efficiencyenvironmental friendly and can be recycled. Catalytic mechanism of ionic liquids in esterification is reviewed. The bottleneck and limitation of ionic liquids application on esterification are addressed. The research direction of ionic liquid in the esterification is also prospected.
