Conversion of 5-hydroxymethylfurfural into 5-ethoxymethylfurfural and ethyl levulinate catalyzed by MOF-based heteropolyacid materials

摘要

Conversion of 5-hydroxymethylfurfural (HMF) into 5-ethoxymethylfurfural (EMF) and ethyl levulinate (EL) is an attractive biomass transformation due to its potential application in the energy and chemical industries. Here, we report on the conversion with MOF-based polyoxometalate [Cu-BTC][ HPM] (NENU-5) as the catalyst. The homogeneous distribution of HPM in the pores of Cu-BTC makes the composite combine the properties of the catalytic activity of HPM and the insolubility, large surface area and hierarchical pores of Cu-BTC. The catalyst demonstrates reusability and catalytic activity with 55% yield of EMF and 11% yield of EL.
