Hydrothermally synthesized catalysts comprising mixed metal oxides can be prepared by the vapor phase oxidation of alkanes or mixtures of alkanes and alkenes in the presence of them to the production of unsaturated carboxylic acids or by the vaporization of alkanes or mixtures of alkanes and alkenes and ammonia to unsaturated nitriles. Used to make furnaces.n n n Mixed metal oxides, gas phase oxidation, unsaturated carboxylic acids, unsaturated nitriles |
