Title
(EN) CLEAVAGE OF METHYLDISILANES, CARBODISILANES AND METHYLOLIGOSILANES WITH ALKALI-AND ALKALINE EARTH METAL SALTS
(FR) CLIVAGE DE MÉTHYLDISILANES, DE CARBODISILANES ET DE MÉTHYLOLIGOSILANES AVEC DES SELS DE MÉTAUX ALCALINS ET ALCALINO-TERREUX
Abstract
(EN)
The invention relates to a process for the manufacture of methylmonosilanes comprising the step of subjecting one or more methyldisilanes, one or more methyloligosilanes, one or more carbodisilanes, or mixtures thereof to cleavage conditions resulting in the cleavage of silicon- silicon bonds or silicon-carbon bonds in carbodisilanes, and optionally a step of separating the resulting methylmonosilanes.
(FR)
L'invention concerne un procédé de fabrication de méthylmonosilanes comprenant l'étape consistant à soumettre un ou plusieurs méthyldisilanes, un ou plusieurs méthyloligosilanes, un ou plusieurs carbodisilanes, ou des mélanges de ceux-ci dans des conditions de clivage conduisant au clivage de liaisons silicium-silicium ou de liaisons silicium-carbone dans des carbodisilanes, et éventuellement une étape consistant à séparer les méthylmonosilanes résultants.
