摘要: Concerns about global warming and energy security have led to the exploration of alternatives to fossil hydrocarbon resources to supply chemicals and energy. Biomass with an estimated global production of around 1.0 × 1011 tons per year has attracted considerable attention as an alternative source for both fuels and chemicals. 5-hydroxymethylfurfural (HMF) from the dehydration of glucose has been one of the most attractive directions for this research. HMF is considered to be a significant precursor for the synthesis of a variety of fine chemicals and none-petroleum-derived polymeric materials (Fig. 1). Many methods have been applied to obtain HMF starting from fructose. Yet, it is clear that large scale, sustainable production of HMF will require glucose as the feedstock. Recently, an ionic liquids system demonstrated that glucose could be effectively converted to HMF in the presence of Lewis acids. However, direct application of Lewis acid catalysts usually leads to discharge of highly toxic byproducts to the environment, contamination of the final product with metal salts, and difficulties in separation. Development of a more environmentally-benign system is strongly preferable in order to realize green and sustainable chemistry. In this work, production of HMF from glucose was studied in ionic liquids in the presence of hydroxyapatite supported chromium chloride using different heating manners including oil-bath heating and microwave irradiation (MI). Compared with oil-bath heating, the MI way obviously increased HMF yield and reduced the reaction time from days to several minutes. A maximum HMF yield of 40% was obtained under MI in 2.5 min from the dehydration of glucose. This method is potential as an energy-efficient and cost-effective approach for the conversion of biomass into platform chemicals.
