  • Process for preparing V-Ti-P catalysts for synthesis of 2,3-unsaturated carboxylic acids
    Patent number: 8765629
    Abstract: The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.
    Type: Grant
    Filed: September 16, 2011
    Date of Patent: July 1, 2014
    Assignee: Eastman Chemical Company
    Inventors: David William Norman, Gerald Charles Tustin, Michael James Nash, Liu Deng, Theresa Sims Barnette
