| 英文摘要 | lignocellulose is generally resistant to dissolving in water and conventional organic solvents, which significantly hinders its efficient utilization. in this work, we provide a novel and efficient technology on lignocellulose dissolution under mild conditions for down-stream conversion with heterogeneous catalysts. in a mixture of hydrogen peroxide, sulfuric acid, ethanol and water, corn straw was completely dissolved in the mixture at 170 degrees c for 120 min without significant volatile chemical production (less than 16%). cellulose and hemicellulose existed as water-soluble oligosaccharides in the solvent, which were more easily converted than the original polymeric carbohydrate. during the dissolved process, peroxide hydrogen exhibited a significant intensification effect on dissolving the hemicellulose, decrystallization of cellulose and delignification with sulfuric acid. furthermore, lignin was destroyed into fragments in the course of dissolution, which had a looser structure and lower molecular weight. |
