| 中文摘要: |
| 木质素是储量丰富的天然芳香族聚合物，且可再生、可降解、无毒，可替代石化原料在化工行业中应用，具有重大环保价值，但天然木质素反应活性较低，直接应用效果不理想，需要通过改性提升其性能。本工作重点总结了木质素的磺化、羟甲基化、脱甲基化、酚化、胺化、酯化、酰化等化学改性方法的研究进展。多种改性方法联合应用、生物改性是木质素改性的重点发展方向。 |
| 英文摘要: |
| Lignin is an abundant natural aromatic polymer with renewability，degradability and non-toxicity.It can replace petrochemical raw materials in the chemical industry and possess significant environmental protection value，however，natural lignin exhibit low reactivity，leading to unsatisfactory direct application effects，and thus require modification to improve its performance.This work focuses on summarizing the research progress of chemical modification methods for lignin，such as sulfonation，hydroxymethylation，demethylation，phenolation，amination，esterification and acylation.The combined application of multiple modification methods and biological modification are the key development directions of lignin modification. |
