An efficient process was developed for the conversion of carbohydrates into 5-hydroxymethylfurfural (HMF) using DMSO as the solvent and an acidic ionic liquid 1-carboxypropyl-3-methyl imidazolium chloride ([CMIm]Cl) as the catalyst. The effects of various reaction parameters on HMF yields were investigated. HMF yields of 95.7% and 88.4% were obtained from fructose and inulin when reactions were carried out 120 degrees C after 120 min and 180 min, respectively. The combination of ZrOCl2 and [CMIm]Cl resulted in a 50.6% yield of HMF from glucose. HMF could also be synthesized using other carbohydrates with moderate to high yields. (C) 2013 Elsevier B.V.
