摘要:

5-羟甲基糠醛(HMF)作为一种基于木质纤维素类生物质的重要平台化合物,是多类高价值化学品和液体燃料的前体,但因理化性质不稳定,其高效制备面临巨大挑战。单一溶剂体系中生物质降解所得HMF产率低且副产物多,在原反应相中加入有机溶剂实现反应过程中HMF的原位萃取可大幅提高其选择性,目前采用双相溶剂体系已成为研究主流。本文在介绍双相溶剂体系、有机溶剂、反应原料、催化剂等影响生物质液相降解制备HMF的基础上,揭示优化反应条件强化两相溶剂界面传质对提高产物产率和反应效率的重要作用,并围绕增强相界面扰动和优化溶剂体系两个主要方面,重点综述了基于传质强化的生物质两相溶剂体系降解制备HMF的研究现状,最后对未来发展趋势进行了展望。

Abstract:

As an important platform compound based on lignocellulosic biomass, 5-hydroxymethylfurfural (HMF) is the precursor of many types of high-value chemicals and liquid fuels. However, due to its unstable physical and chemical properties, efficient preparation of HMF is facing great challenges. In a single solvent system, the yield of HMF from biomass degradation is low, and the yield of by-products cannot be neglected. In-situ extraction of HMF by adding organic solvent in the original reaction phase can greatly improve its selectivity. At present, the use of biphasic solvent system has become the mainstream of research. Based on the discussion of the effects of organic solvents, reaction raw materials, and catalysts on the preparation of HMF by biomass degradation in biphasic solvent system, this article revealed the important effect of optimizing reaction conditions and enhancing the mass transfer of the biphasic solvent interface to increase product yield and reaction efficiency. Focusing on the two vital aspects, the intensification of the phase interface disturbance and optimization of the solvent system, the research status of the degradation of biomass in biphasic solvent system with enhanced mass transfer were reviewed, and finally the future development trend was prospected.

Key words: biomass, 5-hydroxymethylfurfural, biphasic solvent system, transformation in liquid phase, process intensification
