The stability of acid dehydration catalysts based on propylsulfonic acid-modified periodic mesoporous silica in the dehydration of fructose to HMF was evaluated under flow conditions at 130 °C. Hydrophobic catalysts containing ethylene linkers in the silica framework showed improved robustness, particularly towards loss of functional groups from the pore channels.
