| Abstract: | Hydrolysis of cellulose was carried out in 1-n-butyl-3-methylimidazolium chloride catalyzed by acidic ionic liquid 1-n-butyl-3-methylimidazolium hydrogen sulfate （ bmim ] HSO4 ）. Reaction results showed that these parameters including the pre-dissolving time for cellulose, the reaction temperature, the amount of catalyst and water remarkably affected the hydrolysis of cellulose to the reduced sugar. Ninety two percent yield of reduced sugar was obtained by 1.5 g of catalyst and 0.1 mL of water at 90 ℃ with 80 rain of reaction time. |
