| 摘 要： | 在室温离子液体中,以酸功能化离子液体为催化剂进行纤维素的微波辅助降解,分别考察了二甲基亚砜、催化剂和水对纤维素降解的影响.结果表明:纤维素在1-烯丙基-3-甲基咪唑氯盐中的降解效果优于在1-丁基-3-甲基咪唑氯盐中的降解效果;二甲基亚砜能有效地降低体系的黏度,提高降解的效果;酸功能化离子液体的催化效果与其酸性大小相关;微波640 W下添加0.05 g催化剂,0.04 g水,0.6 g二甲基亚砜,反应60 s,纤维素降解效果最佳.

| Abstract: | Hydrolysis of cellulose in room temperature ionic liquids was carried out under microwave irradiation(MW) with sulfonic acid-functionalized ionic liquids(SFILs) as catalysts.The effect of dimethyl sulfoxide loading,water loading and catalyst amount were investigated.The result showed that hydrolysis of cellulose in 1-ally-3-methylimidazolium chloride was better than in 1-butyl-3-methylimidazolium chloride.Dimethyl sulfoxide was able to sharply reduce the viscosity and increase the total reducing sugar yield... |
