  • Recycle process
    Patent number: 7049466
    Abstract: A method for producing an unsaturated carboxylic acid comprises: (a) contacting, in a reaction zone, an alkane with a catalyst containing a mixed metal oxide, under conditions which produce a product gas comprising the unsaturated carboxylic acid, unreacted alkane and a product alkene; (b) recovering unreacted alkane and product alkene from the product gas; and (c) recycling the recovered unreacted alkane and product alkene to the reaction zone; wherein the mixed metal oxide consists of a material having the formula AaMmNnXxOo wherein A is at least one element selected from the group consisting of molybdenum and tungsten, wherein M is at least one element selected from the group consisting of vanadium, cerium and chromium, wherein N is at least one element selected from the group consisting of tellurium, bismuth and selenium, wherein X is at least one element selected from the group consisting of niobium, tantalum, titanium, aluminum, zirconium, chromium, manganese, iron, ruthenium, cobalt, rhodium, nickel,

  • 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.
