Exploring more efficient solvent systems is important for biomass fractionation that can significantly boost the efficiency of biomass catalytic conversion. Ionic liquids (ILs) and deep eutectic solvents (DESs) as novel hydrogen bond based solvents have attracted more and more attention. Research shows that the hydrogen bond between solvents and biomass is the main factor for their excellent performance in biomass fractionation. The cation or anion of ILs can form strong hydrogen bonding with biomass components during the pretreatment processes, which weakens the hydrogen bond interactions between biomass components, and further promotes the destruction of the biomass hydrogen bond network. Similar to ILs, with their designed hydrogen bond donors and acceptors, DESs can also form strong hydrogen bonds with biomass components for fractionation. Herein, this review outlines the recent development of biomass fractionation research through hydrogen‐bond interactions by using ILs and DESs with biomass. This work provides a framework for future investigation of biomass fractionation mechanisms, understanding the effect of ILs/DESs, and exploring more novel efficient biomass catalytic conversion systems.

基于氢键相互作用的新型生物质分馏溶剂系统：综述

探索更有效的溶剂系统对于生物质分馏非常重要，因为它可以显着提高生物质催化转化的效率。作为基于氢键的新型溶剂，离子液体（ILs）和深共熔溶剂（DESs）引起了越来越多的关注。研究表明，溶剂与生物质之间的氢键是其在生物质分馏中优异性能的主要因素。IL的阳离子或阴离子可以在预处理过程中与生物质组分形成牢固的氢键，从而削弱生物质组分之间的氢键相互作用，并进一步促进生物质氢键网络的破坏。与IL相似，DES具有设计的氢键供体和受体，也可以与生物质组分形成强氢键以进行分馏。在此，本综述概述了通过使用IL和DES与生物质通过氢键相互作用进行生物质分馏研究的最新进展。这项工作为今后的生物质分离机制研究，了解ILs / DES的作用以及探索更多新型有效的生物质催化转化系统提供了框架。
