Abstract (en)
[origin: WO2008113729A2] The invention relates to a novel polynary metal oxide phosphate of general formula M<SUB>a</SUB>V<SUB>2</SUB>O<SUB>b</SUB>(PO<SUB>4</SUB>)<SUB>c</SUB> (I), wherein M represents one or more metals selected from the group including V, Cr, Fe, Co, Ni, Ru, Rh, Pd, Cu, Zn, Cd, Hg, Be, Mg, Ca, Sr and Ba, a has a value of 0.5 to 1.5, b has a value of 1.5 to 2.5, 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. Preferred representatives are CoV<SUB>2</SUB>O<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>2</SUB>, NiV<SUB>2</SUB>O<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>2</SUB> or CuV<SUB>2</SUB>O<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>2</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.
