Process for the preparation of organosilicon compounds

This invention relates to the preparation of organosilicon compounds by the addition of a silicon compound containing Si-bonded hydrogen to a compound having an aliphatic multiple bond in the presence of a catalyst which promotes the addition of Si-bonded hydrogen to compounds containing an aliphatic multiple bond. In this process the reactants and the catalyst are continuously introduced into a pipe-shaped reactor while the contents of the reactor, which are maintained in a liquid phase by the application of pressure are circulated in the reactor at a rate of at least 1,000 cm per minute and while the reaction mixture is continuously being removed from the reactor.
