41 - 017Enhancement of the Catalytic Activity of VPO AmmoxidationCatalysts by Use of Vanadyl(IV) Orthophosphate Precursor Com-pounds. — (VO)3(PO4)2·7H2O and (VO)3(PO4)2·9H2O used as precursorcompounds are transformed into highly active ammoxidation catalysts duringdifferent pretreatment procedures. The results of the heterogeneous catalyticammoxidation on the orthophosphate derived catalysts are compared withthose runs obtained by the application of pure (NH4)2(VO)3 (P2O7)2, similartransformation products derived from a VOHPO4·0.5H2O precursor, and pure(VO)2P2O7. — (MARTIN, A.; WOLF, G.-U.; STEINIKE, U.; LUECKE, B.;J.
