摘　　要：系统地从元素组成、结构主体以及主体的联结方式等方面介绍了木质素的结构;并综述了木质素在磺化反应、氧化反应、接枝共聚反应、缩合反应、曼尼希反应、烷基化反应、羟烷基化反应等化学改性反应中的研究进展。通过改变木质素的结构,可以改善木质素的性质,扩大木质素的应用范围,对于天然资源的利用、环境的保护均具有重大意义。引用文献 38篇。The structure of lignin was introduced from its element compositions,structural units and the linkages between these units roundly.The progress in lignin chemical modification was reviewed as well,including sulfonation,oxidation,graft copolymerization,condensation reaction,Mannich reaction,alkylation,hydroxyalkylation,etc.The properties of lignin can be improved by changing its structure,and thus the application can be extended.This is of great significance in natural resource utilization and environment protection.Thirty-eight references are cited.
