Abstract | One-pot achievement of ethyl levulinate from cassava was conducted in ethanol-water system over several simple sulfate salt catalysts. Al-2(SO4)(3) catalyst had the best performance in synthesizing ethyl levulinate comparing with those of a series of sulfate salts. The highest yields of ethyl levulinate was up to 39.27% as well as 7.78% levulinate acid when cassava was catalyzed in ethanol medium by adding 10 wt% water. C-13 and H-1 NMR spectroscopic investigations confirmed that isomerization of glucose to fructose over Al-2(SO4)(3) catalyst is an important step in producing ethyl levulinate and levulinate acid. Due to aggregations of Al3+ under hydrothermal conditions, tiny amount of Al3+ were detected in filtrate at the percentage of 0.32% even if in absolute water. Bronsted and Lewis acids could improve the yield of ethyl levulinate and levulinate acid by synergistic effect. All results suggested that Al-2(SO4)(3) was a simple and efficient catalyst for ethyl levulinate and levulinate acid production.
