摘要
木质素是一种自然界含量丰富的天然芳香族高分子化合物,木质素及其衍生物应用范围极其广阔,因此其分离制备的研究也一直受到国内外学者的青睐,木质素分离制备方法很多,本文主要概述了碱木质素、磺酸盐木质素、有机溶剂木质素和磨木木质素等木质素的提取方法及其研究进展,并对每种方法的优缺点进行了简要的描述。
Lignin was a natural abundant aromatic polymer,and lignin and its derivatives had extremely broad range of applications,so the separation and preparation of the research were favored by domestic and foreign scholars.Lignin can be separated and prepared in many ways.The extraction methods and the reaserch advances of alkali lignin,lignin sulfonate,organic solvents lignin,and mill wood lignin were mainly discribed,and each method＇s good and bad points were briefly described.
