  • Methods for producing unsaturated carboxylic acids and unsaturated nitriles
    Patent number: 6989460
    Abstract: Unsaturated carboxylic acids are produced by the vapor phase catalytic oxidation of mixtures of alkenes and alkanes in the presence of a catalyst containing a mixed metal oxide. Similarly, unsaturated nitriles are produced by the vapor phase catalytic oxidation of alkenes or mixtures of alkenes and alkanes and ammonia in the presence of a catalyst containing a mixed metal oxide.
    Type: Grant
    Filed: November 25, 2003
    Date of Patent: January 24, 2006
    Assignee: Rohm and Haas Company
    Inventors: Leonard Edward Bogan, Jr., Scott Han, Bradley Anson Jacobs, Frederick William Kaiser, Peter David Klugherz, Manhua Lin, Richard David Link, III, Michael William Linsen

  • Calcination
    Publication number: 20020038052
    Abstract: A process for preparing a catalyst is disclosed. The catalyst is useful for the gas phase oxidation of alkanes to unsaturated aldehydes or carboxylic acids or for the ammoxidation of alkanes to unsaturated nitrites.
