木质素是天然芳香族可再生资源,从人类发现木质素到确定它是芳香族化合物,研究其基本官能团种类及化学结构,至今已有180年历史。但由于木质素结构的复杂性和多变性,其研究进展缓慢。笔者阐述了木质素及其化学研究体系的形成,综述了木质素研究的进展,分析了木质素研究的特点和难点,提出了今后木质素研究的方向和热点课题。
Lignin is an abundant natural aromatic renewable resource on earth. A 180-years long history has been past from the discovery of lignin to the determination of lignin aromatic compounds, and its basic types of functional groups and chemical structure. However, the speed of lignin research is slowed down due to the complexity and variability of lignin structure. The author describes the formation of lignin and their chemistry research system, reviews the development of lignin study, analyzes the characteristics and difficulties of lignin research, and highlights future research direction and hot topics.
