摘要
用化学分析、波谱、色谱等手段研究了棉秆碱木素（ＣＳＬ）的特性，推导出ＣＳＬ的Ｃ９单元式，指出ＣＳＬ是一种ＧＳ木素．由于蒸煮过程中的碎片化反应．ＣＳＬ中低分子量的级分含量较高，分子量分布较宽，官能团含量发生变化．蒸煮反应是木素性质发生变化的根本原因．
he charcateristics of cotton stalk soda lignin (CSL) are studied by chemical analyses, spectroscopy and chromatography' It is pointed out that CSL is a kind of GS lignin' Significant condensation anddegradation occur during the cooking process which have changed the content of ' functional groups and led towider molecular weight distribution of CSL. The cooking reaction is the basic cause changing the propertie oflignin
