4种常见木质素有机溶剂法分级的研究进展
Research Progress of Four Common Lignin Fractionated by Organic Solvent Method
摘要
Abstract
With the development of research on lignin-based biomass materials,in order to further improve the performance of lignin-based biomass materials,it is necessary to classify the lignin raw materials.Organic solvent fractionation is a simple and feasible method to obtain lignin with specific physicochemical properties.This paper summarized the research results of classifying 4 kinds of lignin,including sulfate lignin,organic solvent lignin,alkali lignin and enzymolysis lignin,by using organic solvent method in recent years.The molecular weight and molecular weight distribution,as well as the contents of functional groups such as alcohol hydroxyl group,phenol hydroxyl group and me-thoxy group,were used as grading indexes.The characteristics,advantages and disadvantages of single or multiple organic solvents used in different fractionation strategies were compared,and the research on lignin fractionation was briefly summarized and prospected.关键词
