| 摘要:本文首先基于酸性低共熔溶剂（ADESs）中氢键受体和氢键供体的多样性，总结了普通ADESs、Lewis-ADESs和Brønsted-ADESs在木质纤维生物质预处理过程中的特点，并归纳了ADESs在木质素提取和增值利用领域的研究进展。然后，针对国内外多种ADESs提取木质素的评价方法进行综述，如DFT理论、Kamlet-Taft参数、核磁共振技术（NMR）、傅里叶变换红外光谱（FT-IR）等，探讨了各评价方法的机理及应用情况。最后，从ADESs对木质素结构及木质素溶剂化过程影响的角度，对未来高效和可持续的木质素提取与木质素增值利用进行展望，以期为相关领域的研究提供一定的参考。 |
| Abstract: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 structure as well as the lignin solvation process， with a view to providing certain references for the research in related fields. |
