Title
(DE) VERFAHREN ZUR VERMINDERUNG DES GEHALTS AN BORVERBINDUNGEN IN HALOGENSILAN ENTHALTENDEN ZUSAMMENSETZUNG
(EN) PROCESS FOR REDUCING THE CONTENT OF BORON COMPOUNDS IN HALOSILANE-CONTAINING COMPOSITIONS
(FR) PROCÉDÉ POUR DIMINUER LA TENEUR EN COMPOSÉS DE BORE DANS UNE COMPOSITION CONTENANT DE L'HALOGÉNOSILANE
Abstract
(DE)
Die Erfindung betrifft Verfahren zur Verminderung des Gehalts an Borverbindungen in einer zumindest ein Halogensilan enthaltenden Zusammensetzung, umfassend ein Inkontaktbringen der Zusammensetzung mit mindestens einem Phenylsilan und ein Abtrennen des zumindest einen Halogensilans. Ferner betrifft die Erfindung die Verwendung von Phenylsilanen zur Entfernung von Borverbindungen aus Halogensilan enthaltenden Zusammensetzungen.
(EN)
The invention relates to processes for reducing the content of boron compounds in a composition containing at least one halosilane, comprising contacting the composition with at least one phenylsilane and removing the at least one halosilane. The invention further relates to the use of phenylsilanes for removal of boron compounds from compositions containing halosilane.
(FR)
L'invention concerne un procédé pour diminuer la teneur en composés de bore dans une composition contenant au moins un halogénosilane, le procédé comprenant une mise en contact de la composition avec au moins un phénylsilane et une séparation du ou des halogénosilanes. L'invention concerne en outre l'utilisation de phénylsilanes pour éliminer les composés de bore de compositions contenant de l'halogénosilane.
