  • Method for the continuous production of silicon compounds bearing amino groups
    Patent number: 7842831
    Abstract: N-organylaminoorganyl- and N,N-diorganylaminoorganyl-triorganylsilanes are prepared continuously with high space/time yield, high product purity, and low halide content, while simultaneously increasing process safety, by introducing haloalkyltriorganylsilane and a 1 to 100 fold motor excess of organylamine into a continuous reactor with a residence time which may be less than 10 minutes, thus minimizing competing side reactions.
    Type: Grant
    Filed: November 24, 2005
    Date of Patent: November 30, 2010
    Assignee: Wacker Chemie AG
    Inventors: Thomas Kornek, Jochen Rauch

  • Preparation of alkylamines
    Patent number: 6806379
    Abstract: A continuous process for preparing alkylamines comprises reacting continuous streams of ammonia and alkyl halide in a molar ratio of at least 10:1 in a pressure reactor. The ultimate reaction mixture has a temperature of >80° C., a pressure of >40 bar and an ammonium halide content of >1% by weight, and comprises two phases (A) a first phase comprising at least 75% by weight of the total amount of ammonium halide formed, and (B) a second phase comprising at least 80% by weight of the total amount of alkylamine formed. The first and second phases are separated, and an alkylamine product is recovered therefrom.
