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
