| 摘 要： | 用硝基苯氧化法分析了三倍体毛白杨的木素单元结构,并对三倍体毛白杨进行了硫酸盐法和碱性亚钠-蒽醌法制浆,提取了两种未漂浆的浆中残留木素,用红外光谱和13C-NMR详细分析了其结构,研究结果表明:和普通毛白杨相此,三倍体毛白杨木素缩合型结构的比例较高;和硫酸盐法制浆相比,碱性亚钠-蒽醌法制得的浆中含有较少的木素缩合结构和木素-碳水化合物复合体(LCC),羧基含量较低。这些研究结果为进一步研究三倍体毛白杨浆漂白性能打下基础。

| Abstract: | In order to understand the detailed properties of pulping and bleatching about triploid clones Populus tomentosa Carr., the lignin structure of it was analysed by nitrobenzene oxidation, and the residual lignins in unbleached pulp by KP and AS-AQ were extracted, the residual lignins were analysed by FT-IR and I3C-NMR, the results indicated that triploid clones Populus tomentosa Carr. had more condensed lignin structure as compared with conventional aspen species and the pulp by AS-AQ had less condensed lignin structure, lignin-carbonhydrate complex (LCC) and carboxy group as compared with pulp by KP. |
