Abstract

Vanadium phosphate catalysts prepared from VOPO4. 2H(2)O are described anddiscussed. The use of H4P2O7 as a phosphorus source, as compared with H3PO4, is shown to give an improved synthesis of VOPO4 . 2H(2)O. Reduction of VOPO4. 2H(2)O with alcohols from both the materials leads to the formation of VOHPO4.0.5H(2)O. However, the material derived from H4P2O7 has a higher intrinsic activity (mol maleic anhydride formed per unit surface area) than that derived from H3PO4. The final catalysts are shown to comprise (VO)(2)P2O7 together with a range of V(V) VOPO4 phases and the origin of the enhanced activity is discussed in terms of the catalyst structure.
