Title (EN) PREPARATION OF ORGANOHALOSILANES
(FR) PRÉPARATION D'ORGANOHALOGÉNOSILANES
Abstract: front page image
(EN)A process for preparing organohalosilanes comprising combining hydrogen, a halosilane having the formula HaSiX4-a (I), and an organohalide having the formula RX (II), wherein R is C1-C10 alkyl or C4-C10 cycloalkyl, each X is independently halo, and the subscript a is 0, 1, or 2, in the presence of a sufficient amount of a catalyst effective in enabling the replacement of one or more of the halo groups of the halosilane with the R group from the organohalide, at a temperature from 200 to 800 °C, to form an organohalosilane and a hydrogen halide, wherein the volumetric ratio of hydrogen to halosilane is from 1 :3 to 1 :0.001 and the volumetric ratio of hydrogen to organohalide is from 1 : 1 to 1 :0.001, and wherein the catalyst is optionally treated with the hydrogen or the halosilane prior to the combining.
(FR)La présente invention porte sur un procédé de préparation d'organohalogénosilanes consistant à combiner de l'hydrogène, un halogénosilane de formule HaSiX4-a (I), et un organohalogénure de formule RX (II), dans laquelle R est un groupe alkyle en C1-C10 ou cycloalkyle en C4-C10, chaque X étant indépendamment un halogène, et l'indice a valant 0, 1, ou 2, en présence d'une quantité suffisante d'un catalyseur efficace pour permettre le remplacement d'au moins un des halogènes de l'halogénosilane par le groupe R de l'organohalogénure, à une température de 200 à 800 °C, pour former un organohalogénosilane et un halogénure d'hydrogène, le rapport volumétrique de l'hydrogène à l'halogénosilane étant compris entre 1:3 et 1:0,001 et le rapport volumétrique de l'hydrogène à l'organohalogénure étant compris entre 1:1 et 1:0,001, et le catalyseur étant éventuellement traité avec l'hydrogène ou l'halogénosilane avant la combinaison.
