Research Progress on the Classification of Deep Eutectic Solvents and Their Dissolution of Lignin

低共熔溶剂(DESs)作为一种绿色溶剂,具有低毒性、可设计性、价格低和生物可降解等特点。为更好地发展绿色溶剂体系,本文从小分子溶剂到大分子溶剂体系的设计思路着手,简要介绍了DESs的制备方式,阐述了不同DESs,包括传统DESs、低共熔超分子聚合物(DESPs)和聚低共熔溶剂及其部分应用。随后,着重介绍了传统DESs在木质纤维素预处理方面的应用,综述了传统DESs结构对溶解和提取木质素影响的应用进展。最后,展望了DESs的设计合成及其对木质素溶解和提取方面的研究方向。

Deep eutectic solvents(DESs),as the green solvents,are characterized by low toxicity,designability,affordability and biodegradability.To better develop the green solvent systems,starting with the design ideas of small molecular solvent to macromolecules solvent systems,this paper briefly introduced the preparation methods of DESs,and described different DESs,including traditional DESs,deep eutectic supramolecular polymers(DESPs),poly-deep eutectic solvents and some of their applications.Subsequently,the application of traditional DESs in lignocellulose pretreatment was emphatically introduced,and progress in the application of the effect of traditional DESs structure on the dissolution and extraction of lignin was reviewed.Finally,the design and synthesis of DESs and their research work on lignin dissolution and extraction were summarized and prospected.
