  • Method for the production of polymerizable silicones
    Patent number: 8110697
    Abstract: Polymerizable siloxy-substituted silanes are obtained in high yield and purity by adding a substituted alkoxysilane to a mixture of disiloxane, acetic acid, sulfuric acid, and optionally an acidic catalyst, separating a product phase from an acidic phase, adding hexamethyldisilazane to the product phase and filtering off a resulting salt, followed by distillation.
    Type: Grant
    Filed: January 8, 2008
    Date of Patent: February 7, 2012
    Assignee: Wacker Chemie AG
    Inventors: Markus Jandke, Florian Koopmann, Birgit Peschanel
  • Method for the production of polymerizable silicones
    Patent number: 8101789
    Abstract: Siloxy-substituted silane-containing polymerizable silicones are prepared in high purity by metering a substituted alkoxysilane into a mixture of disiloxane, acetic acid, and acid catalyst, adding acetyl chloride, separating an acidic phase from a product phase, and adding hexamethyldisilazane to the product phase, which is then distilled.
