Carbohydrate

or sugar-derived compounds were used as environmentally friendly additives for the depolymerization of Kraft lignin waste and organosolv lignin prepared from Miscanthus giganteus. The yields of the aromatic monomer obtained from Kraft lignin increased from 5.1 to 49.2% with the addition of mannitol, while those obtained from organosolv lignin increased from 44.4 to 83.0% with the addition of sucrose. This enhanced lignin depolymerization was also confirmed by gel permeation chromatography and nuclear magnetic resonance spectroscopy. The above results clearly indicate the beneficial effects of carbohydrate derivatives on the lignin depolymersization process, more specifically, suggesting that the presence of carbohydrates improve the lignin depolymerization of lignocellulose.

使用碳水化合物衍生物改善木质素废料的催化解聚

糖类

或糖衍生的化合物被用作环境友好的添加剂，用于解聚牛皮木屑和由芒草（Miscanthus giganteus）制备的有机溶剂木质素的解聚。通过添加甘露糖醇，从牛皮纸木质素获得的芳族单体的产率从5.1增加到49.2％，而通过添加蔗糖，从有机溶剂木质素获得的芳族单体的产率从44.4％增加到83.0％。通过凝胶渗透色谱法和核磁共振波谱法也证实了这种增强的木质素解聚。以上结果清楚地表明了碳水化合物衍生物对木质素解聚过程的有益作用，更具体地，表明碳水化合物的存在改善了木质纤维素的木质素解聚。
