Abstract

A process for preparing an orthosilicic acid tetraalkyl ester having 2 to 6 carbon atoms in the ester group which comprises contacting metallic silicon with an alcohol corresponding to the ester group in the presence of the corresponding alkali alcoholate: PA1 A. in the presence of a surface active substance; PA1 B. in the presence of a compound containing a methoxy group; or PA1 C. under pressure at a temperature above the boiling point of the reaction mixture.
