Abstract
Abstract SiO 2 -SO 3 H, with a surface area of 115 m 2 /g, pore volumes of 0.38 cm 3 g −1 and 1.32 mmol H + /g, was used as a 10% w/w catalyst for the preparation of 5-hydroxymethyl-2-furfural (HMF) from fructose. A conversion of 100% was achieved in a microwave reactor during 10 min at 150 °C in DMSO, with 100% selectivity for HMF, at a molar ratio of fructose: DMSO equal to 1:56. The catalyst could be re-used three times.
