摘要/Abstract

摘要： 采用球磨方法分离并提纯出棉秆全秆磨木木质素(MWL)和棉秆秆芯MWL。采用紫外光谱和红外光谱对上述分离出的木质素进行分析。并用¹³CNMR作了进一步分析研究。从分析结果看出:棉秆木质素属于愈疮木基-紫丁香-对羟苯基(GSH)型。棉秆秆皮和秆芯木质素结构不同,在秆皮中存在较多的紫丁香基结构单元和少量的对羟苯基结构,而秆芯中以紫丁香基结构单元和愈疮木基结构单元为主。

关键词: 棉秆, 磨木木质素, 光谱分析

Abstract: Milled-wood lignins from whole cotton stalk and cotton stalk core respectively were isolated and purified through ball-milling,etc.These lignins were analyzed by means of ultraviolet spectroscopy, infrared spectroscopy and ¹³CNMR. The results indicated that lignins of cotton stalk are of guaiacyl-syringyl-parahydroxy phenylpropane(GSH) type. There are less parahydroxy phenylpropane and more syringyl units in lignin of cotton stalk bark and more syringyl and guaiacyl units in lignin of cotton stalk core.

Key words: cotton stalk, milled wood lignin, spectroscopic analysis
