中文摘要：

甘蔗渣 EMAL (enzymatie hydrolysis/mild acidolysis 木质素) 的 ehemical 结构是有 31P-NMR 的揭示份量上， DFRC (减少的劈开跟随的 derivatization ) 。甘蔗渣和甘蔗渣 EMAL 的 thermochemical 特征与 thermogravimetry 被评估。结果证明甘蔗渣 EMAL 被 guaiacyl 和 syringyl 单位的酉分的氢氧根组主要形成。在甘蔗渣 EMAL 的 DBDO 内容被发现是 0.180 mmol 路 g ? 1。在提高的温度下面的甘蔗渣 EMAL 的分解 characteristies 与甘蔗渣的不同。关键词甘蔗渣 - 木质素 - 化学结构 - 31P-NMR - DFRC - thermogravimetry

英文摘要：

The chemical structures of bagasse EMAL （enzymatic hydrolysis/mild acidolysis lignin） were revealed quantitatively with ^31p-NMR, DFRC （derivatization followed by reductive cleavage）. The thermochemical characteristics of bagasse and bagasse EMAL were evaluated with thermogravimetry. The results show that bagasse EMAL is mainly formed by the phenolic hydroxyl group of guaiacyl and syringyl units. The DBDO content in bagasse EMAL was found to be 0.180 mmol.g^-1. The decomposition characteristics of bagasse EMAL under elevated temperature were much different from that of bagasse.
