| 摘 要： | 结合前人的研究成果综述了各种草木原料中半纤维素的类型、结构形式及制备方法,特别指出在造纸原料和纸浆中存在部分半纤维素与木质素发生化学键连接形成了木质素-碳水化合物复合体(LCC),还对纸浆中的半纤维素对浆性能所产生的影响加以阐述,针对半纤维素在造纸工业中所引起的"假木质素"问题总结出相应的应对策略.此外,还概述了从草木原料中制备粗半纤维素的分离方法以及对其进一步纯化的技术,对半纤维素的检测手段也做了介绍.

| Abstract: | The types,structures characterization and separation of hemicelluloses from various kinds of wood and straw materials have been summarized based on pioneer's study.Covalent linkages between part of hemicellulose and lignin have been proposed to exist in plant materials and in chemical pulp and formed lignin-carbohydrate complex(LCC)structure.The mechanical properties of pulp was influenced by hemicelluloses in pulps which was introduced.The modified Kappa number method was used for determination of "true" lignin content in pulps.In addition,isolation methods of hemicelluloses from wood and non-wood materials and their futher purification and detection have also been outlined. |
