环丁砜辅助促进纤维素水解变糖效率研究

Improved hydrolysis of cellulose to reducing sugars with sulfolane

通过在纤维素水解体系中引入非质子型溶剂环丁砜,提升了纤维素的水解变糖效率,将纤维素发生快速水解的临界聚合度由51提升至64。经催化转化后,纤维素转化率和还原糖产率最高分别达到98.1%和74.8%。

By adding sulfolane,an aprotic solvent,into the system for hydrolyzing cellulose,the efficiency of saccharification was improved,and the critical degree of polymerization for rapid hydrolysis of cellulose was increased from 51to64.After the catalytic conversion of cellulose,the highest conversion and total reducing sugars yield were 98.1% and74.8% respectively.
