  • Catalytic (AMM)oxidation process for conversion of lower alkanes to carboxylic acids and nitriles
    Publication number: 20060020142
    Abstract: An improved single-step catalytic (amm)oxidation process for the conversion of one or more C3 to C5 alkanes, in the presence of supercritical fluid, to one or more (amm)oxidation products, such as unsaturated carboxylic acids and unsaturated nitriles.

  • Modified catalysts and process
    Publication number: 20050203312
    Abstract: Modified metal oxide catalysts are disclosed which have different chemical, physical and catalytic properties, when used for catalytic conversions of carbon based compounds, as compared to corresponding unmodified metal oxide catalysts. Methods for preparing the modified catalysts are described and their utility in catalytic process 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.
