Selective dehydration of glucose to 5-hydroxymethylfurfural on acidic mesoporous tantalum phosphate

[EN]Mesoporous tantalum phosphate was prepared from tantalum tartrate and ammonium phosphate monobasic in the presence of an ionic surfactant at room temperature, and subsequent calcined at 550 °C. This solid exhibits a high specific surface area (256 m2 g−1) and strong acidity (1.48 mmol NH3 g−1),...

This solid exhibits a high specific surface area (256 m2 g−1) and strong acidity (1.48 mmol NH3 g−1), and it has been successfully used as solid acid catalyst in the dehydration of glucose to 5-hydroxymethylfurfural (HMF) in a biphasic water/methyl isobutyl ketone medium.
