Claims
- 1. In a process for the preparation of epoxy group-containing alkoxy silanes by hydrosililation of a terminally unsaturated epoxy compound with a hydro-alkoxy silane using a platinum catalyst, the improvement which comprises carrying out the hydrosilylation in the presence of an alcohol in an amount of from 0.2 to 10 moles, per mole of the hydro-alkoxy silane, said alcohol being selected from the group consisting of methanol, ethanol, n-propanol and isopropanol.
- 2. The process in accordance with claim 1 wherein the terminally unsaturated epoxy compound is allylglycidylether, 4-vinylcyclohexene-1-oxide, 1,3butadiene oxide, divinylbenzene oxide, 1,5-nexadiene oxide, i,4-pentadiene oxide, 3-methyl-1,3-butadiene oxide or allyl(alpha-methylglycidyl)ether.
- 3. The process in accordance with claim 1 wherein the hydro-alkoxy silane is trimethoxysilane, or ethoxysilane, methyldimethoxysilane or ethyldiethoxysilane.
- 4. The process in accordance with claim 1 wherein the platinum catalyst is hexachloroplatinic acid, a complex of a platinum chloride with an unsaturated ketone, a complex of a platinum chloride with a beta-diketone, a complex of a platinum chloride with an olefin or a complex of a platinum chloride with an amine.
