Abstract: Maleic anhydride is made from n-butane or n-butene in a tubular reactor having an undivided reaction zone which contains two different catalysts-the first catalyst converts at least part of the n-butane or n-butene to butadiene and the second catalyst converts at least part of this product to maleic anhydride.

Abstract: Molybdenum containing oxidation catalysts are prepared by reducing hexavalent molybdenum to a valence state below +6 prior to or during the catalyst preparation. Reproducible catalysts with superior catalytic activity are conveniently made by this process.

Abstract translation: 含钼氧化催化剂通过在催化剂制备之前或期间将六价钼还原成低于+6的价态来制备。 通过该方法可方便地制备具有优异催化活性的可再现催化剂。
