Yang, Shuhua published the artcileStudy on the influence of different catalysts on the preparation of ethyl levulinate from biomass liquefaction, Safety of Ethyl 4-oxopentanoate, the main research area is ethyl levulinate biomass liquefaction heating.
The liquefaction experiments of straw biomass under heating and pressure were carried out with sulfuric acid and three ionic liquids as catalysts, 1-Butyl-3-methylimidazolium chloride ([BMIM] [Cl]), 1-Butyl-3-methylimidazolium hydrogen sulfate ([BMIM] [HSO4]), 1-methyl-3-(4-sulfobutyl) imidazole bisulfate ([HSO3-BMIM] [HSO4]), and anhydrous ethanol as solvent. The effects of catalyst type and dosage, reaction time and reaction temperature on liquefaction were investigated and optimized. The results showed that under the catalysis of sulfuric acid, the yield of Et levulinate was the highest; [HSO3-BMIM] [HSO4], the conversion of raw materials was the highest; when sulfuric acid was used as catalyst, the optimum reaction conditions were catalyst dosage 10%, reaction temperature 190 °C, reaction time 60 min, the yield of Et levulinate (EL) was 18.11%, and the conversion of raw materials was 75%. When [HSO3-BMIM] [HSO4] was used as catalyst, the optimum reaction conditions were as follows: catalyst dosage 26%, reaction temperature 200 °C, reaction time 60 min, the yield of EL was 10.2%, conversion of raw material 85.31%.
