  • Porous silica microsphere scavengers
    Patent number: 7041623
    Abstract: Highly purified, porous silica microspheres contain functional groups which are capable of selectively binding to reaction impurities, such as excess reactant or reaction by-products, which are contained in a reaction medium. The reaction impurities can thereby be efficiently removed from the reaction medium, providing a convenient method for product purification.
    Type: Grant
    Filed: October 23, 2002
    Date of Patent: May 9, 2006
    Assignee: Agilent Technologies, Inc.
    Inventors: Joseph J. Kirkland, Timothy J. Langlois, Ounjie Wang
