  • Method for hydrogenating higher halogen-containing silane compounds
    Patent number: 9561965
    Abstract: The present invention relates to a continuous process for hydrogenating halogen-containing silane compounds having at least three silicon atoms, in which at least one halogen-containing silane compound having at least three silicon atoms and at least one hydrogenating agent are converted continuously to form at least one hydridosilane compound having at least 3 silicon atoms and oxidized hydrogenating agent, and wherein oxidized hydrogenating agent is withdrawn and reduced, and the reaction product of this reduction reaction is sent back to the hydrogenation, to the hydridosilane compounds obtainable by this process and to the use thereof.
    Type: Grant
    Filed: November 27, 2013
    Date of Patent: February 7, 2017
    Assignee: Evonik Degussa GmbH
    Inventors: Min-Zae Oh, Jens Haubrock, Thorsten Schwaertzke, Imad Moussallem, Martin Trocha
  • Method for producing acrylic acid
    Patent number: 9309180
    Abstract: Method for producing acrylic acid by dehydration of a C3 hydroxycarboxylic acid, characterized in that dehydration is achieved by contacting, at a temperature of more than 150° C., the hydroxycarboxylic acid with a mixture which is liquid at this temperature and comprises at least one metal salt of a C3 hydroxycarboxylic acid, and water.
    Type: Grant
