摘要：

Here we represented the heteropoly acids (HPAs) and polyoxometalate (POM)-based ionic liquids (ILs) catalyzed the effective alcoholysis of furfural alcohol (FAL) to alkyl levulinate. H5AlW12O40 exhibited the highest catalytic activity among HPAs, furnishing > 99% FAL conversion and 80% yield of butyl levulinate (BL). The incorporation of IL framework containing sulfate group into HPAs resulted in the enhanced catalytic performance. [MIMBS](5)[AlW12O40] achieved the highest BL yield of 94% and maintained a good catalytic activity after 6 times of recycle and reuse experiments. The effect of the Hammett acidity and structure of catalyst on the catalytic performance of HPAs and POM-based ILs was also investigated.
