PREPARATION OF ORGANOHALOSILANES

摘要

IN A PROCESS FOR PREPARING OGANOHALOSILANES BY REACTING METALLIC SILICON PARTICLES WITH AN ORGANOHALIDE IN THE PRESENCE OF A COPPER CATALYST, A CONTACT MASS COMPOSED OF THE METALLIC SILICON AND THE CATALYST FURHTER CONTAINS A MINUTE, BUT EFFECTIVE AMOUNT OF A CATALYTIC METAL POWDER WHICH HAS BEEN PRODUCED BY AN ATOMIZING TECHNIQUE. THE PROCESS IS SUCCESSFUL IN DRASTICALLY INCREASING A FORMATION RATE WITHOUT LOWERING THE SELECTIVITY OF USEFUL SILANE.
