5-由木质纤维素生物质产生的羟甲基糠醛（HMF）和乙酰丙酸（LA）可以催化升级为有价值的化学品和燃料。木质纤维素生物质被认为是化石能源的替代碳源。本文综述了木质纤维素生物质生产羟甲基糠醛和乳酸的最新进展，重点介绍了木质纤维素生物质的预处理、羟甲基糠醛和乳酸的制备原理以及其改性应用。传统上，HMF和LA的制备由无机酸在水溶液中催化。近年来，使用有机溶剂作为反应介质的研究已有许多报道。详细总结了有机溶剂中均相和非均相催化剂制备HMF和LA的工艺，指出了不同反应体系的优势和挑战。此外，还详细介绍了HMF和LA的应用。
5-Hydroxymethylfurfural (HMF) and levulinic acid (LA), produced from lignocellulosic biomass, can be catalytically upgraded to valuable chemicals and fuels. Lignocellulosic biomass has been considered as an alternative carbon resource for fossil. This work reviews the recent development of HMF and LA production from lignocellulosic biomass, which focuses on pretreatment of lignocellulosic biomass, preparation principle for HMF and LA and the upgrading application. Traditionally, the preparation of HMF and LA is catalyzed by mineral acids in aqueous solutions. Recently, using organic solvents as reaction medium have been investigated in many reports. We carefully summary the production process of HMF and LA with homogeneous or heterogeneous catalysts in organic solvents; meanwhile, the advantages and challenges in different reaction systems are also pointed out. Furthermore, the applications of HMF and LA are described in details.
