ABSTRACT:
The present invention is processes for preparing silanes from the reaction of silicon monoxide with hydrogen halides. In a first embodiment of the instant invention, silicon monoxide is reacted with a hydrogen halide to produce silanes and halosilanes. In a second embodiment of the instant invention, the silicon monoxide is activated by heating in an inert atmosphere prior to contact with the hydrogen halide. In a third embodiment of the instant invention, a catalyst is employed which enhances conversion of silicon monoxide to silanes and modifies process selectivity for silane products. The catalyzed process can be run with activated or non-activated silicon monoxide.
