    摘要: Vanadium-containing catalysts are obtained by using polyvanadic acid as a source of vanadium. Vanadium-containing catalysts are obtained by mixing catalyst components other than vanadium, or their precursors, with a polyvanadic acid sol which is formed by ion-exchanging a metavanadic acid aqueous solution with a proton-type cation-exchange resin and performing polycondensation, and by drying and/or calcining the mixture. Such vanadium-containing catalysts can fully exhibit their catalytic activity under mild reaction conditions, and can be suitably used for various reactions, such as synthesis of phthalic anhydride by the partial oxidation of o-xylene, synthesis of benzaldehyde by the partial oxidation of toluene, synthesis of benzoic acid by the partial oxidation of toluene, synthesis of anisaldehyde by the partial oxidation of p-methoxy toluene, synthesis of propylene by the oxidative dehydrogenation of propane, synthesis of isobutene by the oxidative dehydrogenation of isobutane, synthesis of methyl formate by the oxidative dehydrogenation of methanol, and synthesis of acrylonitrile by the ammoxidation of propane.

    摘要: A solid acid-base catalyst contains vanadium pentoxide hydrate. Moreover, it is preferable that the vanadium pentoxide hydrate in the solid acid-base catalyst has a composition which is represented by the following general equation (1): V2O5.nH2O  (1) (n: 0.1-3). Creation of the vanadium pentoxide hydrate was confirmed by measuring X-ray diffraction spectrum shown in FIG. 1. In accordance with the above arrangement, the solid acid-base catalyst can sufficiently display catalytic activity under mild conditions, and it can be suitably applied to various reactions, such as the syntheses of olefins or ethers through dehydration reactions of alcohols, the syntheses of aldehydes or ketones through dehydrogenation reactions of alcohols, hydrations and isomerization reactions of olefins, alkylations, esterifications, amidations, acetalizations, aminations, hydrogen shift reactions, aldol condensation reactions and polymerization reactions.
