  • Aqueous hexasubstituted guanidinium chlorides and methods for their preparation and use
    Patent number: 6235934
    Abstract: Hexasubstituted guanidinium chlorides are prepared by a method which affords them in high yield as aqueous solutions, optionally also containing alkali metal chlorides. The solutions may be employed as sources of hexasubstituted guanidinium salts useful as phase transfer catalysts for the reaction of alkali metal salts of dihydroxyaromatic compounds with substituted imides to form polyetherimides or their intermediates.
    Type: Grant
    Filed: December 17, 1998
    Date of Patent: May 22, 2001
    Assignee: General Electric Company
