2) residual lignin
残余木素
1.
The residual lignin of triploid clones of Populus tomentosa from kraft pulp( KP) and sulfite pulp(ASP),as well as the lignin in the waste liquor was isolated and analyzed by Fourier transform infrared((FT-IR))spectrum and()~(13)C nuclear magnetic resonance(NMR).
该文用核磁共振(13C--NMR)及红外光谱(FT--IR)等手段,探讨了人工培育的速生材———三倍体毛白杨硫酸盐及碱性--亚钠两种制浆方法中,浆中残余木素及废液中木素的结构。
2.
The residual lignin of reed kraft pulp was extracted with dioxane and water,then treated with laccase and NHA system.It was found that the methoxyl group and phenol hydroxyl group contents of biodegraded reed kraft pulp lignin are lower,alcohol hydroxyl group content is higher compared with the lignin before biotreatment.Benzenering open reaction was also found during the laccase/NHA treatment
用溶剂抽提法制取苇浆残余木素,用漆酶/助剂和氧气与其反应,通过甲氧基的测定、元素分析、13C-NMR、1H-NMR、IR分析苇浆残余木素与漆酶/助剂反应前后其结构的变化。

分子式:
分子量:
CAS号:
性质:纸浆的一种。以芦苇和荻等为原料,常用硫酸盐法或亚硫酸盐法制得。纤维形态和纸浆质量与一般草浆差不多,但杂细胞含量较少,滤水性和机械强度也较好。漂白的苇浆可用于制造一般书写纸的印刷纸等。
