  • Process of manufacturing organosilicon products with improved quality using heterogeneous precious metal catalysts
    Patent number: 8497338
    Abstract: A process for manufacturing an organosilicon product having a stabilized low color and no formation of black particles during storage includes (a) reacting an unsaturated compound with a silicon compound having a reactive Si—H bond under hydrosilylation conditions in a reaction zone in the presence of a heterogeneous precious metal catalyst to provide an organosilicon product having a color of less than 40 pt/co; (b) separating the heterogeneous precious metal catalyst from the organosilicon product; and (c) recovering the heterogeneous precious metal catalyst.
    Type: Grant
    Filed: October 31, 2011
    Date of Patent: July 30, 2013
    Assignee: Momentive Performance Materials Inc.
    Inventors: He Bai, Kevin L. Bobbitt, Michael R. Powell

  • Process for producing epoxyorganosilicon compounds
    Publication number: 20020103323
    Abstract: The present invention describes a method for producing epoxyorganosilicon compounds through the platinum-catalyzed hydrosilation reaction of ethylenically unsaturated epoxides and a silicon-hydride in the presence of a carboxylic acid salt. Also taught herein is the use of carboxylic acid salts in compositions of epoxyorganosilicon compounds to provide compositions of greater stability.
