  • Method for the production of trichlorosilane
    Patent number: 8197784
    Abstract: High yields of trichlorosilane are achieved in the reaction of tetrachlorosilane and hydrogen at a temperature in the range of 900° C. to 1300° C. and a pressure above the critical pressure of the reactants.
    Type: Grant
    Filed: October 12, 2007
    Date of Patent: June 12, 2012
    Assignee: Wacker Chemie AG
    Inventors: Bernhard Pfluegler, Robert Ring
  • Process for preparing trichloromonosilane
    Patent number: 8043591
    Abstract: A process for preparing trichloromonosilane, in which silicon particles are reacted with hydrogen chloride in a fluidized bed reactor, wherein the silicon particles used are a silicon dust which is obtained as a waste product in the preparation of defined silicon particle size fractions from lump-form silicon and the silicon dust is introduced directly into the reactor.
