Abstract
An improvement in a process for forming an orthosilicic acid ester or an oligomer thereof by contacting a tetrachlorosilane or higher homolog thereof with a primary alcohol, the improvement which comprises introducing the alcohol directly into a tetrachlorosilane liquid phase without said alcohol touching the gas phase and, after completion of the reaction, removing hydrogen chloride formed during the reaction from the reaction zone.
