Abstract: The invention relates to a novel polynary metal oxide phosphate of general formula MaV4-aOb(PO4)c (I), wherein M represents one or more metals selected from the group including Ti, Zr, Hf,Cr, Fe, Co, Ni, Ru, Rh, Pd, Cu, Zn, B, Al, Ga and In, a has a value of 0 to 2.0, b has a value of 2.0 to 4.0, c has a value of 2.0 to 4.0, said novel compound having a crystal structure and being characterized by defined diffraction reflexes in powder X-ray diffraction. Preferred representatives are V4O3(PO4)3, CrV3O3(PO4)3, FeV3O3(PO4)3 and TiV3O3(PO4)3. The metal oxide phosphates are suitable as gas phase oxidation catalysts, e.g. for producing maleic anhydride from a hydrocarbon with at least four carbon atoms.

Abstract: The invention relates to a novel polynary vanadyl pyrophosphate of general formula (VO)a(M1-bVb)2(P2O7)c (I), wherein M represents one or more metals selected from the group including Ti, Zr, Hf, Cr, Fe, Co, Ni, Ru, Rh, Pd, Cu, Zn, B, Al, Ga and In, a has a value of 0.5 to 1.5, b has a value of 0 to 0.9, c has a value of 1.5 to 2.5, said novel compound having a crystal structure and being characterized by defined diffraction reflexes in powder X-ray diffraction. A preferred representative is (VO)Fe2(P2O7)2. The vanadyl pyrophosphates are suitable as gas phase oxidation catalysts, e.g. for producing maleic anhydride from a hydrocarbon with at least four carbon atoms.
