Abstract
1,237,159. Tetra-alkyl silicates. DYNAMIT NOBEL A.G. 15 Aug., 1969 [17 Aug., 1968], No. 40897/69. Heading C3S. Tetra-alkyl orthosilicates are prepared by reacting silicon, iron silicide or ferrosilicon in particulate form with a saturated aliphatic alcohol in the presence of the corresponding alkoxide of an alkali metal, there being present throughout the reaction at least 70% by weight of the tetra-alkyl silicate based on the total weight of liquid present. This liquid consists of silicate plus alcohol. The process may be continuous or batchwise and is carried out at the boiling temperature of the reaction mixture. An apparatus is described for carrying out the process. Reference has been directed by the Comptroller to Specifications 1,204,309 and 1,193,727.
