Disclosed is an improved process for the slurry phase Direct Synthesis of trialkoxylanes which comprises the activation of copper catalyst and silicon with a reducing agent such as hydrogen gas, carbon monoxide or monosilane. Such activation affords high, stable reaction rates and selectivities and high silicon overall conversion especially in alkylated benzene solvents.

Procédé amélioré pour la synthèse directe en suspension de trialcoxysilanes, consistant à activer un catalyseur au cuivre et du silicium avec un agent réducteur, comme l'hydrogène gazeux, le monoxyde de carbone ou le monosilane. Cette activation permet d'obtenir des vitesses de réaction stables et élevées ainsi qu'une forte sélectivité, avec un taux global élevé pour la conversion du silicium, notamment dans les solvants à base de benzène alkylé.
