摘要:
A novel polynary metal oxide phosphate of the general formula I MaV4-aOb(PO4)c is described, in which M is one or more metals selected from Ti, Zr, Hf, Cr, Fe, Co, Ni, Ru, Rh, Pd, Cu, Zn, B, Al, Ga and In, a is from 0 to 2.0, b is from 2.0 to 4.0, c is from 2.0 to 4.0, having a crystal structure whose powder X-ray diffractogram is characterized by defined reflections. 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, for example for preparing maleic anhydride from a hydrocarbon having at least four carbon atoms.
