Abstract
Procédé pour l'obtention d'orthosilicates de tétra-alkyle dont le constituant ester contient 2 à 6 atomes de carbone, par réation du silicium métallique sur un alcool en présence d'au moins 70 % de l'orthosilicate de tétraalkyle désiré et d'un aloolate alcalin correspondant à l'alcool utilisé. On conduit la réaction en présence d'un catalyseur supplémentaire choisi parmi les éthers-alcools et les acanolamines. Application à la production industrielle d'orthosilicate de tétraéthyle.
