PREPARATION OF ORGANOHALOSILANES

摘要

WHEN OGANOHALOSILANES ARE PREPARED BY CHARGING A REACTOR WITH A CONTACT MASS CONTAINING A METALLIC SILICON POWDER AND A COPPER CATALYST, AND INTRODUCING AN ORGANOHALIDE-CONTAINING GAS INTO THE REACTOR TO EFFECT THE DIRECT REACTION, A POLY(ORGANO) PHOSPHINO COMPOUND OS ADDED TO THE CONTACT MASS. THE INVENTION IS SUCCESFUL IN PRODUCING ORGANOHALOSILANES AT A SIGNIFICANTLY IMPROVED PRODUCTION RATE WITHOUT REDUCING THE SELECTIVELY OF USEFUL SILANE.
