  • Process of making mixed metal oxide catalysts for the production of unsaturated aldehydes from olefins
    Patent number: 7494952
    Abstract: The present invention is for a process for making a catalyst for production of unsaturated aldehydes, such as methacrolein, by gas phase catalytic oxidation of olefins, such as isobutylene, said catalyst containing oxides of molybdenum, bismuth, iron, cesium, tungsten, cobalt, nickel, antimony, magnesium and zinc. The process is a synthesis of the catalyst with aging or digestion of the reaction slurry with little or no agitation. A catalyst precursor is formed from the water insoluble and water soluble components and is dried. The metal oxide catalyst is formed by calcination of the catalyst precursor.
