Abstract

The acid-catalysed, aqueous phase dehydration of xylose (a monosaccharide obtainable from hemicelluloses, eg, xylan) to furfural was investigated using vanadium phosphates (VPO) as catalysts: the precursors, VOPO4· 2H2O, VOHPO4· 0.5 H2O and VO (H2PO4) 2, and the materials prepared by calcination of these precursors, that is, γ-VOPO4,(VO) 2P2O7 and VO (PO3) 2, respectively. The VPO precursors were completely soluble in the reaction ...
