摘要
5-羟甲基糠醛(HMF)是一种重要的生物基材料单体,具有非常广泛的应用价值。果糖等己糖选择性脱水是制备5-羟甲基糠醛的主要方法之一。本文首先从催化剂的角度出发,介绍了近年来不同均相和多相酸性催化剂在该反应中的应用。按照反应溶剂体系进行分类,总结了近年来该领域中不同溶剂体系的研究进展,包括双相溶剂体系、亚/超临界流体溶剂体系和离子液体溶剂体系等。最后,指出了新型多相酸性催化剂以及高效溶剂体系的开发和改进是该领域将来主要的研究方向。
5-Hydroxymethylfurfural（HMF） is a kind of important monomer of biomaterials and possesses wide application value. Selective dehydration of hexose, such as D-fructose, is one of main synthetic methods for 5- hydroxymethylfurfural. This paper first systemically introduces the recent applications of different homogeneous and heterogeneous acid catalysts in this yield. Then, it reviews the recent development of different reaction solvent systems applied in this reaction, including bi-phase solvent systems, sub/supereritical fluid solvent systems, ionic liquid solvent systems and so on. At last, it points out that the future study direction in this yield is the exploitation and improvement of new heterogeneous acid catalysts as well as highly efficient solvent systems.
