Abstract

The present invention relates to a process wherein a mixture containing (A) organosilicon compounds selected from (Al) organosilanes (A2) organosiloxanes with the proviso that component A has at least 0.01 - 4 mole of alkoxy groups per mole of silicon atoms and that at least a part of the organosilicon compounds of the component A comprises Si-bonded hydrogen, (B) at least 0.5 mole of water per mole of alkoxy groups in component A, and (C) optionally a water-miscible solvent, is reacted in the presence of (D) ammonia, a primary or secondary C1-C4-alkylamine or a compound which liberates ammonia or primary or secondary C1-C4-alkylamine on reaction with water to form organopolysiloxanes containing Si-bonded hydroyen.
