"Oxidation catalyst and precursor, production methods,Processes for conversion of hydrocarbons to the product partially oxidized and oxidation processes of hydrocarbon C ~ 3 ~ C ~ 4 ~ to a mixture containing acid and maleic anhydride acrylic paint, respectively.A catalyst is active and selective partial oxidation of hydrocarbons comprises a polioxometalato activated partially reduced, preferably, polioxomolibdato of niobium.It is prepared from a polioxou00e2nion appropriate,It was exchanged with a cation is appropriate and activated by heating to a temperature effective activation in the presence of a reducing agent is suitable as piridu00ednio.The hydrocarbons C ~ 3 ~ C ~ 4 ~ may be partially oxidised selectively to acrylic acid and maleic acid.
