摘要：

纤维素作为可再生资源,其催化水解得到的平台化合物对缓解能源压力具有重要的意义。本文以生物质竹子为原料选择700 ℃预碳化、150 ℃磺化得到的固体炭磺酸为基体,负载1-丁基-3-甲基咪唑氯后得到离子液体功能化固体炭磺酸催化剂。结果表明,催化剂最优条件下水解纤维素得到的总还原糖产率相对于固体炭磺酸提升了15.2%,循环使用后,依然表现出良好的催化性能。

Abstract:

Cellulose is a renewable resource. Compounds obtained by the hydrolysis of cellulose are of great significance to ease the energy pressure. Herein, the hydrolysis of cellulose catalyzed by solid carbon sulfonic acid supported 1-butyl-3-methylimidazolium chloride is reported. The solid carbon sulfonic acid obtained from bamboo biomass by pre-carbonization at 700 ℃ and sulfonation at 150 ℃ was used as the matrix. Ionic liquid functionalized solid carbon sulfonic acid catalyst was obtained by loading 1-butyl-3-methylimidazolium chloride. The results show that the total reducing sugar yield under optimal conditions is increased by 15.2% relative to the total reducing sugar yield by exploiting solid carbon sulfonic acid. The catalyst still exhibits good performance after recycling.

Key words: solid carbon sulfonic acid, ionic liquids, hydrolysis of cellulose
