Abstract:
1. A process for preparing a catalyst for the oxidation of an alkane, alkene or mixtures thereof, the process comprising the steps of: (a) admixing metal compounds, at least one of which is oxygen containing compound, and at least one solvent to form a solution; (b) removing the solvent from the solution to obtain a catalyst precursor; and (c) calcining the catalyst precursor at a temperature from 350° C. to 850° C. under an inert atmosphere to form a mixed-metal oxide catalyst having the formula wherein, when a=1, b=0.01 to 1.0, c=0.01 to 1.0, d=0.01 to 1.0, e=0.01 to 1.0, and f is dependent upon the oxidation state of the other elements, said catalyst further characterized by having at least two crystal phases, the first crystal phase being an orthorhombic M1 phase and the second crystal phase being a pseudo-hexagonal M2 phase, said orthorhombic M1 phase present in an amount between greater than 60 weight percent to less than 90 weight percent and wherein said catalyst exhibits a chemisorption of NH
