ABSTRACT:
A catalyst comprising a mixed metal oxide is useful for the vapor phase oxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated carboxylic acid and for the vapor phase ammoxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated nitrile. The catalyst is treated with a source of hydrogen, an alcohol, a source of NOxor a mixture thereof.
