Title (EN) METHOD OF MAKING A HALOSILOXANE
(FR) PROCÉDÉ DE FABRICATION D'UN HALOSILOXANE
Abstract:
(EN) A method of producing a halosiloxane, the method comprising: i) combining water, a halosilane, and a first solvent to form a reaction mixture, ii) partially hydrolyzing and condensing the halosilane to form a reaction product mixture comprising the halosiloxane, the solvent, unreacted halosilane, and hydrogen halide, iii) adding a second solent, where the second solent has a boiling point the boiling point of the halosiloxane, to the reaction mixture in i) or to the reaction product mixture in ii), and iv) recovering the halosiloxane from the reaction product mixture.
(FR) L'invention concerne un procédé de production d'un halosiloxane, le procédé comprenant les étapes consistant à : i) combiner de l'eau, un halosilane et un premier solvant pour former un mélange réactionnel, ii) hydrolyser partiellement et condenser l'halosilane pour former un mélange de produits de réaction comprenant l'halosiloxane, le solvant, l'halosilane n'ayant pas réagi et l'halogénure d'hydrogène, iii) ajouter un second solvant, le second solvant ayant un point d'ébullition, le point d'ébullition de l'halosiloxane, au mélange réactionnel dans i) ou au mélange de produits de réaction dans ii), et iv) récupérer l'halosiloxane à partir du mélange de produits de réaction.
