英文摘要: Al-2(SO4)(3) was developed as a simple and efficient catalyst for the synthesis of methyl levulinate (MLE) from carbohydrate biomass including fructose, glucose, mannose, sucrose, cellobiose, starch, and cellulose. The maximum MLE yield of 64% from glucose could be obtained at 160 degrees C for 150 min. Important roles of Al3+ and Bronsted acid sites generated by the hydrolysis/methanolysis of Al3+ were elucidated. The reaction process was revealed using in situ real-time attenuated total reflection infrared spectroscopy. Al-2(SO4)(3) can be regenerated easily and reused at least four times without the loss of activity. (C) 2014 Elsevier B.V. All rights reserved.
