  • Polymer-supported transition metal catalyst complexes and methods of use
    Patent number: 8921486
    Abstract: A catalyst composition comprising a polymer functionalized with a ligand for binding a transition metal containing compound to form a transition metal complex, wherein said functionalized polymer has a number average molecular weight of about 5,000 to 30,000 g/mol and a polydispersity index of about 1.0 to 2.0. The catalyst is used in a hydroformylation reaction, preferably one in which the liquid phase has been volumetrically expanded with a compressed gas, is readily recyclable using nanofiltration.
    Type: Grant
    Filed: November 16, 2009
    Date of Patent: December 30, 2014
    Assignee: University of Kansas
    Inventors: Jon Tunge, Bala Subramaniam, Jing Fang, Ranjan Jana
