<p>Various processes for modifying metal oxide catalysts, in particular Mo-V-Nb based catalysts, are disclosed. The processes include treatment with a pyridine solution, refluxing in oxalic acid and methanol, and cryo-grinding. The utility of the modified catalysts in catalytic processes is described. Alkenes, unsaturated saturated carboxylic acids, saturated carboxylic acids and their higher analogues are prepared directly from corresponding alkanes, alkenes or alkanes and alkenes utilizing using one or more modified metal oxide catalysts.</p> |
