摘要: 对从杨树心、边材提取的磨木木质素进行了元素分析和红外光谱 (FTIR)、质子和碳-13核磁共振波谱 (1H、13 C NMR)等化学特征研究。研究结果表明:杨树心、边材木质素的经验式分别为C9H7.16O2.3 8(OCH3) 1.99和 C9H8.6 1O2.73 (OCH3) 1.3 3 。心材木质素甲氧基含量 2 8.16%,比边材高8.73 %。

Abstract: Milled wood lignins (MWLs)extracted from poplar I 214Populus×euramericana(Dode) Guineir cv.'I 214' heartwood and sapwood were characterized by elemental analysis,FTIR, 1H and 13 C NMR spectroscopy.The results showed that the methoxyl content in heartwood lignin was 8.73% higher than that in sapwood lignin,and the C 9 empirical formula for heartwood lignin and sapwood lignin were C 9H 7 16 O 2 38 (OCH3) 1 99 and C 9H 8 61 O 2 73 (OCH3) 1 33,based on methoxyl and elemental analysis.The free aliphatic hydroxyl groups per C 9 unit (OH aliph) were 78.2% in total numbers of hydroxyl groups of heartwood lignin,and the free phenolic hydroxyl groups(OH ph)were 21.8%.The OH aliph were 79.2% and the OH ph were 20.8% in sapwood lignin.The hearwood lignin showed 55.5% guaiacyl units and 44.5% syringyl units in the aromatic region.The sapwood lignin showed 61 3% guaiacyl units and 38 7% syringyl units.The FTIR, 1H and 13 C NMR spectra showed both lignins belong to typical hardwood lignin. heartwood and sapwood were characterized by elemental analysis,FTIR, 1H and 13 C NMR spectroscopy.The results showed that the methoxyl content in heartwood lignin was 8.73% higher than that in sapwood lignin,and the C 9 empirical formula for heartwood lignin and sapwood lignin were C 9H 7 16 O 2 38 (OCH3) 1 99 and C 9H 8 61 O 2 73 (OCH3) 1 33,based on methoxyl and elemental analysis.The free aliphatic hydroxyl groups per C 9 unit (OH aliph) were 78.2% in total numbers of hydroxyl groups of heartwood lignin,and the free phenolic hydroxyl groups(OH ph)were 21.8%.The OH aliph were 79.2% and the OH ph were 20.8% in sapwood lignin.The hearwood lignin showed 55.5% guaiacyl units and 44.5% syringyl units in the aromatic region.The sapwood lignin showed 61.3% guaiacyl units and 38.7% syringyl units.The FTIR, 1H and 13 C NMR spectra showed both lignins belong to typical hardwood lignin.
