Process for preparing organosilicon compounds having Si-bonded hydrogen atoms

摘要: A process for preparing organosilicon compounds having Si-bonded hydrogen atoms comprises, in a first step, reacting silanes of the general formula R 1 SiX 3-a , where R. is monovalent hydrocarbon radical free from aliphatic multiple bonds, terminal unsaturated radical, X halogen atom or --OR 2 and 0 1; with at least two per molecule; presence catalysts which promote addition to an bond; removing excess by distillation, ratio employed double bond silane compound 1.0 2.0; second resultant hydrolyzable groups H b 3-b SiZ siloxanes SiOSiR Z 3 ; 2; water; hydrolysis, Si latter obtained step 0.8 5.0, proviso that have on average 4 molecule.
