摘要： 以离子液 1-丁基-3-甲基咪唑氯为纤维素溶剂, 酸性离子液 1-磺酸丁基-3-甲基咪唑氯为催化剂进行了纤维素水解反应. 通过筛选, 找到了合适的离子液共溶剂二甲基甲酰胺可降低纤维素-离子液体系的黏度. 分别考察了催化剂用量和水含量对纤维素水解的影响, 同时研究了高聚合度的滤纸及棉花的水解行为. 应用二硝基水杨酸法测得水解体系中还原糖的浓度, 进而求得反应过程中还原糖的收率. 结果表明, 在酸性离子液中水解纤维素是完全可行的, 最高可达到 95%的还原糖收率.

Abstract: The hydrolysis of cellulose in acid ionic liquids was investigated systematically. Ionic liquid 1-butyl-3-methylimidazolium chloride was used as the solvent of cellulose, and acid ionic liquid 1-butyl sulfonic acid-3-methylimidazolium chloride was used as the catalyst. It was proved that this novel hydrolysis process is totally feasible, and total reducing sugar yield is up to 95%.

Key words: cellulose, hydrolysis, ionic liquid, acid ionic liquid, total reducing sugar
