Research Progress on Acidic Deep Eutectic Solvents for Lignin Extraction
In this paper,based on the diversity of hydrogen bond acceptors,and hydrogen bond donors in acidic low-eutectic solvents (ADESs),the characteristics of common ADESs,Lewis-ADESs and Brønsted-ADESs in the pretreatment process of lignocellulosic fiber biomass were summarized and the research progress in the field of lignin extraction,and value-added utilization were studied. Then,the valuation methods of DFT theory,Kamlet-Taft parameters,nuclear magnetic resonance technique (NMR),and Fourier transform infrared spectroscopy (FT-IR) for lignin extraction by ADESs at home and abroad were reviewed,the mechanism and application of each evaluation method were discussed. Finally,the future efficient and sustainable lignin extraction,and value-added lignin utilization were envisioned,from the perspective of the effects of ADESs on the lignin struc-ture as well as the lignin solvation process,with a view to providing certain references for the research in related fields.
