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

性质:主要指由苯酚和水解木质素在酸性催化剂存在下作用而成的树脂。其性能接近普通的热塑性酚醛树脂。收获率大约是苯酚的两倍,在节约苯酚和甲醛方面具有很大的经济意义。用碱性木质素与苯酚和乌洛托品制成树脂,同样可以节约苯酚和甲醛。这些树脂可用于压塑粉和木质素塑料。
