Abstract

Alkylhalogenosilanes are prepared by heating an alkyl halide with a contact mass consisting of silicon and a metal catalyst, e.g. copper or silver, characterized by the step of discharging the contact mass from the heating zone as soon as about 90 per cent of the silicon in the contact mass is consumed. The alkyl halide may then be brought into contact with fresh contact mass. The main product is dialkyldihalogenosilane while alkyltrihalogeno- and trialkylhalogeno-silanes are formed in small proportions. In the example methyl chloride is reacted with silicon and copper.
