Abstract (en)

[origin: WO2008113728A2] The invention relates to a novel polynary metal oxide phosphate of general formula M<SUB>a</SUB>(VO)(P<SUB>2</SUB>O<SUB>7</SUB>)b(PO<SUB>4</SUB>)<SUB>c</SUB> (I), wherein M represents one or more metals selected from the group including V, Ti, Zr, Hf, Cr, Fe, Co, Ni, Ru, Rh, Pd, Cu, Zn, Cd, Hg, B, Be, Mg, Ca, Sr and Ba, a has a value of 1.5 to 2.5, b has a value of 0.5 to 1.5, c has a value of 0.5 to 1.5, said novel compound having a crystal structure and being characterized by defined diffraction reflexes in powder X-ray diffraction. A preferred representative is Fe<SUB>2</SUB>VO(P<SUB>2</SUB>O<SUB>7</SUB>)(PO<SUB>4</SUB>). 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.
