Abstract: A continuous process for preparing silanes and siloxanes having SiOC groups which comprises (a) introducing in a liquid phase a chlorosilane and a hydroxyl-containing aliphatic compound in parallel flow into a first stage of a first reactor in an amount such that from 0.5 to 0.

Abstract: A process for the addition of Si-bonded hydrogen to an aliphatic multiple bond in the presence of a platinum catalyst which is obtained by dissolving a platinum halide in at least 20 parts by weight of olefin for each part by weight of the platinum halide, and subsequently heating and mixing the solution obtained with from 0.5 to 1 mole of a primary and/or secondary amine for each gram atom of platinum.

Abstract: 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.
