Abstract:

An efficient process for the dehydration of fructose to 5-hydroxymethylfurfural(5-HMF) in ionic liquid 1-butyl-3-methyl-imidazolium chloride([BMIM]Cl) in the presence of ion-exchange resin was deve-loped. A 5-HMF yield of 78.0% was achieved in 10 min at 100 ℃, where the reaction time required was much lower than that reported in previous works for converting fructose to 5-HMF. No remarkably decrease in 5-HMF yield occurred for initial fructose concentrations up to 20%(mass fraction). The ionic liquid and ion-exchange resin could be recycled and exhibited constant activity for 9 successive trials.

Key words: Fructose; 5-Hydroxymethylfurfural; Ionic liquid; 1-Butyl-3-methyl-imidazolium chloride; Ion-exchange resin
