摘要
介绍了经双核锰络合物催化的过氧化氢的漂白是一种前景可观的技术。它具有一定的环境效益 ,同时在高度脱木素作用下 ,碳水化合物无严重的降解 ,且残余木素在脱木素前后从浆中分离出来。采用1H和13 C核磁共振光谱联用来分析脱木素期间木素的结构变化。
Hydrogen peroxide delignification catalyzed by [LMn (Ⅵ(μ-O) 3Mn(Ⅵ)](ClO 4)(abbreviated as Mn_MeDTNE) is a promising technology,because of not only its environmental advantages,but also its high degree of delignification without severe degradation of carbohydrates.Valuable in formation has been obtained.In addition,residual lignin was isolated from pulp before and after delignification by cellulase hydrolysis.These lignin preparations were analyzed by 1H and 13 C correlation 2D NMR for the elucidation of the structural changes of lignin during the delignification.
