摘要：
The present invention uses a nitrogen-containing organic compound to be reacted with an alkyl sultone to obtain a zwitterion compound. The zwitterion compound is reacted with a heteropoly acid (HPA) to obtain an ionic liquid HPA (IL-HPA). The IL-HPA is used for acetylation of polyol and HOAc for obtaining polyol acetate. The IL used in the reaction can be recycled. Thus, problems of product separation, waste acid handling, and corrosion of facilities are solved and production through esterification is improved with a green catalysis.
