Efficient synthesis of 5-hydroxymethylfurfural from mannose with a reusable MCM-41-supported tin catalyst

The Sn/MCM-41 catalyst was demonstrated to be effective for the conversion of mannose into 5-HMF, with comparable performances to those of reported heterogeneous catalysts. The Sn/MCM-41 catalyst was reusable without significant loss of activity after eight consecutive runs.
