  • Catalysts selective for the preparation of mixed ketones from a mixture of carboxylic acids
    Patent number: 7659432
    Abstract: Mixed ketones are prepared from a mixture of carboxylic acids in a process with high selectivity by using an improved catalyst. The catalyst contains zirconium dioxide or zirconium dioxide and titanium dioxide, and a Group 1 or 2 metal silicate or phosphate salt. The new catalyst is more selective toward the formation of the mixed ketone, as opposed to a symmetrical ketone.
    Type: Grant
    Filed: July 1, 2008
    Date of Patent: February 9, 2010
    Assignee: Eastman Chemical Company
    Inventors: Alexey V. Ignatchenko, Michelle Manichanh King, Zhufang Liu, Calvin W. Whiddon
