Abstract:
1. A process for producing an unsaturated carboxylic acid which comprises subjecting an alkane, or a mixture of an alkane and an alkene, to a vapor phase catalytic oxidation reaction in the presence of a catalyst produced by the process comprising: (a) providing a mixed metal oxide having the empirical formula A (b) contacting said mixed metal oxide with a liquid contact member selected from the group consisting of organic acids, alcohols, inorganic acids and hydrogen peroxide to form a contact mixture; (c) recovering insoluble material from said contact mixture; (d) calcining said recovered insoluble material in a non-oxidizing atmosphere; (e) admixing said calcined recovered insoluble material with (f) removing said at least one solvent from said so-formed admixture to form a catalyst precursor; and (g) calcining said catalyst precursor.
