Abstract
Official abstract text for this publication.
Organosilicon compounds bearing SiOC groups and having low residual silicon-bonded chlorine are prepared continuously by reacting a chlorosilane with alcohol and optionally water by contacting a gaseous phase containing alcohol with a liquid phase containing silane, organosilicon intermediates, organosilicon compounds containing SiOC groups and optional inert solvent in a reaction column in which the gas phase passes through the liquid phase in bubble form, or is provided with a vaporizer operating by a crossflow principle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for continuously preparing compounds containing SiOC groups, comprising: reacting a silane having silicon-bonded chlorine atoms with an alcohol and optionally also with water to release gaseous hydrogen chloride, at least part of the reaction being performed in a reaction column in which a gaseous phase contains a total of at least 80% by weight of alcohol, hydrogen chloride, any water, and any inert gas, and a liquid phase contains a total of…
