Abstract:

Different types of ionic liquids in catalytic esterification reactions are summarized. Traditional catalysts are often troubled by more side reactions，high corrosiveness，environmental pollution，separation difficulty，and cannot be recycled. Contrarily，ionic liquids show good thermal stability，high efficiency，environmental 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.
