应用傅里叶转换红外光谱(FTIR)和X射线光电子能谱(XPS), 研究了3种提纯方法得到的竹木质素及其化学反应产物的化学结构特性. 确定竹木质素C1s的电子结合能分别为283.52 (C—H或C—C), 284.58～285.72 (C—OR或C—OH), 286.10～286.44 (C＝O或HO—C—OR), 287.65～287.72 (O—C＝O) eV. O1s的电子结合能分别为530.31(羟基氧原子), 531.45～531.72(醛或酮的羰基氧原子), 532.73～533.74(酯键或羧酸中的羰基氧原子) eV. 竹木质素中的结构单元之间主要是通过醚键和碳碳单键连接, 慈竹磨木木质素结构单元中醚键、碳碳单键、酯键、羰基和烯双键的比例为100∶63∶32∶40∶32 (49.3∶31.0∶16.0∶19.9∶16.0)

he structure of three kinds of milled wood lignin and its chemical products was studied by FTIR and XPS. The binding energy of C1s was assigned to 283.52 (C—H or C—C), 284.58～285.72 (C—OR or C—OH), 286.10～286.44 (C＝O or HO—C—OR), 287.65～287.72 (O—C＝O) eV and O1s binding energy was to 530.31 (O—H), 531.45～531.72 (RC＝O), 532.73～533.74 (O—C＝O) eV respectively. Bamboo lignin was bound mainly through ester linkage and C—C bonds. The proportion of ether, C—C bond, ester, carbonyl and unsaturated double bonds is 100∶63∶32∶40∶32 (49.3∶31.0∶16.0∶19.9∶16.0) correspondingly.
