METHOD OF PREPARING HEXAETHOXY DISILANE Russian patent published in 1997 - IPC

Abstract RU 2087476 C1

FIELD: manufacture of solar batteries. SUBSTANCE: hexaethoxy disilane is prepared by esterification of hexachlorodisilane with alcohol. Esterification is carried out by simultaneously and uniformly feeding hexachlorodisilane and absolute alcohol into reaction zone at molar ratio of 1:(6.20-6.35) and simultaneously removing the resulting hydrogen chloride. EFFECT: greater process efficiency and greater purity of the desired product. 3 cl, 1 tbl
