Abstract
The hydrolysis of cellulose into platform compounds and chemicals fuels has gained much attention to relieve the global energy crisis and environmental pollution. The filter paper (FP) cellulose with average degree of polymerization (DP) of 1000-1300 was dissolved in 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) firstly. And then acidic ionic liquids (ILs), ([(CH2)3SO3HVIm]HSO4) as the catalyst was applied to hydrolyze the FP cellulose by microwave heating. Compared with the oil bath heating method, microwave heating could effectively increase the total reducing sugars (TRS) yield about 10.7%. When the ratio of ILs catalyst to FP (w/w) was 0.167, and the ratio of deionized water to FP (w/w) was 0.833, the TRS yield was up to 60.8% within 20 min at 100°C.
