摘要: Abstract The dehydration of fructose or glucose to 5-hydroxymethylfurfural (5-HMF) using room temperature ionic liquids (ILs) as a solvent is promising method for producing liquid fuels from renewable resources. IL, 1-hydroxyethyl-3-methylimidazolium tetrafluoroborate ([C 2 OHMIM]BF 4 ), was used catalyst—rather than solvent—in the conversion 5-HMF. With glucose, yield 5-HMF reached high 67.3% after 1 h at 180 °C in dimethylsulfoxide (DMSO) solvent. catalyst separated reaction mixture by distilling and reused six times without loss activity. Furthermore, kinetic analysis carried out illustrate formation 5-HMF, values activation energy pre-exponential factor were 55.77 kJ mol –1 1.6 × 10 min respectively.
