Synthesis of 5-hydroxymethylfurfural (HMF) from carbohydrate is one of vital step for bio-refinery development. In this work, a novel strategy was developed for catalytic conversion of fructose to HMF in 2-butanol. The inexpensive ionic liquids were used to adjust the acidity of biobased acid catalyst for enhancing the dehydration of fructose to HMF. The combination of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) with oxalic acid afforded an excellent HMF yield of 97.1% at 98.7% fructose conversion under mild conditions of 100°C and 60 min, owing to the enhanced dissociation ability of oxalic acid by [Bmim]Cl. A possible dissociation mechanism of oxalic acid induced by [Bmim]Cl was proposed based on control experiments and detailed analyses with NMR and FT-IR techniques. It involved that the [Bmim]Cl interacted with oxalic acid through hydrogen bond, which decreased the electron d. of oxygen atom on hydroxyl group and weakened the O-H bond, thus making the hydrogen in the O-H group to easily dissociate in the form of H+. Moreover, the reusability of oxalic acid and [Bmim]Cl was demonstrated, and both could be reused up to six times without significant loss in activity. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Recommanded Product: 65039-09-0
