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