  • Method for the production of isocyanatoorganosilanes
    Patent number: 7576228
    Abstract: A process for preparing isocyanoatoorganosilanes by thermolysis of carbamatoorganosilanes in the presence of microwave radiation, optionally employing homogeneous or heterogeneous catalysis, provides isocyanatoorganosilane product in higher yield than prior art thermolyses, and with fewer byproducts. A continuous process is thus possible.
