低共熔溶剂应用于木质纤维素预处理的研究进展

Research Progress on the Application of Deep Eutectic Solvent in Lignocellulose Pretreatment

低共熔溶剂(DES)是一种新型的绿色溶剂,具有制备简单、价格低廉、无毒、可生物降解、可循环使用的特点,在木质纤维素预处理应用方面前景广阔。本文首先概述了低共熔溶剂的组成、分类、制备方法及其物理性质等,随后对DES在生物质预处理领域中的研究应用进行归纳,综述了DES预处理分离木质纤维素的机理性研究,重点介绍了DES选择性分离木质纤维素的应用进展,以期为DES在预处理木质纤维素类生物质的规模化应用提供理论参考。

Deep eutectic solvent(DES)was a new type of green solvent,which was simple preparation,low cost,non-toxic,biodegradable,recyclable,etc,and had broad prospects in the application of lignocellulose pretreatment.In this paper,the composition,classification,preparation methods and physicochemical properties of DES were summarized.Subsequently,the research and application of DES in the field of biomass pretreatment were reviews.The mechanistic of DES pretreatment and separation of lignocellulose were concluded.The application progress of DES selectively separating lignocellulose was mainly introduced in order to provide theoretical reference for large-scale application of DES in pretreatment of lignocellulosic biomass.
