    摘要： 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 0.9 gram-mole of hydroxyl group is present per gram-atom of Si-bonded chlorine; (b) removing the liquid reaction mixture from the first reactor; (c) introducing the reaction mixture at the head of a column used as the second reactor which is maintained at an elevated temperature; (d) adding a hydroxyl-containing aliphatic compound as a gas at the lower end of the column or at a point between the lower end and the upper end of the lower one-third of the column, in an amount at least sufficient to completely react with the Si-bonded chlorine present in the reaction mixture obtained from the first stage and (e) removing the silane containing SiOC groups or polysiloxane containing SiOC groups from the column at a point below the point of addition of the hydroxyl-containing aliphatic compound.

    摘要： 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.
