Microwave irradiation technology was used to assist the conversion of cellulose to methyl levulinate (ML) in methanol solution in the presence of mixed catalysts. The reactions were carried out in a microwave reactor and cellulose was rapidly converted into ML with a highest yield of 61.5% by the use of SnCl4/H2SO4 as catalyst. The catalysts ratios, reaction time and reaction temperature were optimized and found to have great influences on both the ML product yield and the selectivity. Besides, an appropriate amount of water, which may participate the breakage of the glucosidic bond of cellulose, is highly desirable for the full conversion of cellulose. Several other biomass derived carbohydrates such as starch, sucrose and inulin were also tested in the optimized system and 48%~60% ML yields were achieved. Finally, the mixed catalysts can be recycled and reused for at least five times without much decrease in catalytic activity.

Key words: cellulose, methyl levulinate, microwave irradiation, alcoholysis
