低共熔溶剂中单糖制备5-羟甲基糠醛研究进展

Progress in the Preparation of 5-hydroxymethylfurfural from Monosaccharides in Deep Eutectic Solvents

在“绿色溶剂”—低共熔溶剂(Deep Eutectic Solvent,DES)中,以可再生能源生物质为原料制备重要平台化合物5-羟甲基糠醛(5-Hydroxymethylfurfural,5-HMF)是化石燃料转型以及实现可持续发展的重要途径之一。本文综述了果糖和葡萄糖在DES中催化转化制备HMF的研究进展,着重介绍DES的优点及单糖在DES成分氯化胆碱存在下催化制备HMF的机理,为进一步优化DES及反应介质条件提供了研究基础,同时对下一步研究发展方向进行了展望。

The preparation of the important platform compound 5-hydroxymethylfurfural(5-HMF)from renewable biomass in deep eutectic solvents(DES),a"green solvent",is one of the most important ways for the transition from fossil fuels and the realization of sustainable development.In this paper,the research progress of HMF preparation by catalytic conversion of fructose and glucose in DES is reviewed,and the advantages of DES and the mechanism of HMF preparation catalyzed by monosaccharides in the presence of choline chloride,a component of DES,are highlight-ed,which provides a research basis for the further optimization of DES and the conditions of the reaction medium,and the direction of the next step of the research is also prospected.
