| 摘 要： | 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. 结果表明，与硫酸盐浆（KP）相比，碱性-亚钠法浆（ASP）中残余木素含有较少的缩合型结构以及木素与半纤维素的连接； 两种废液木素中都含有大量的苯环及甲基、亚甲基结构，几乎不存在烷基芳基醚键结构；与KP相比，ASP废液中木素含有较多的羧基、缩合型愈创木基结构以及愈创木酚型的伯醇醚.

| Abstract: | 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).Results showed that the condensed structure and the connection between lignin and semi-cellulose in ASP were less than those in KP.A large number of structures of benzene,methyl and methylene groups,but rare aralkyl ether linkage existed in the waste liquor.There were more carboxyl groups, condensed guaiacyl units and guaiacyl primary alcohol in the waste ASP liquor than those in KP waste liquor. |

| Keywords: | triploid clones of Populus tomentosa residual lignin condensed structure |
