More Information
Summary:The invention relates to a catalyst for producing maleic anhydride by heterogeneous catalytic gas phase oxidation of a hydrocarbon with at least for carbon atoms, which contains a catalytically active substance containing vanadium, phosphorous, iron and oxygen, the catalytically active substance having an iron/vanadium atom ratio of 0.005 to < 0.05, and Fe(III) phosphate is used as an iron feed stock. The invention also relates to a number of methods for producing the inventive catalyst and to the use of the catalyst for producing maleic anhydride.
