| Résumé : | A novel method has been developed for the direct conversion of fructose into 5-(ethoxymethyl)furfural (EMF) catalyzed by an organic–inorganic hybrid solid catalyst [MIMBS]3PW12O40. First, etherification of 5-(hydroxymethyl)furfural (HMF) by ethanol was studied over a series of catalysts, and [MIMBS]3PW12O40 showed the best catalytic activity with an EMF yield of 90.7% at 70 °C. Then the one-pot dehydrative etherification of fructose into EMF was studied. It indicated that a low temperature (70 °C) was not favored for the dehydrative etherification process, and a high temperature (110 °C) was favored to promote side reactions. A high EMF yield of 90.5% was obtained from fructose at 90 °C with 5 mol % catalyst for 24 h. The recycling test demonstrated that [MIMBS]3PW12O40 could be reused several times without losing catalytic activity, with an average EMF yield of approximate 90%. This work provides a meaningful method for the conversion of carbohydrates into fine chemicals and biofuel additives. |
