| 摘要 |
The present invention relates to a method for production of alkylhalosilanes by reaction between elemental silicon and an alkylhalide at elevated temperatures in the presence of a copper-based catalyst and optionally promotors. Aluminium in the form of metallic aluminium, or an aluminium alloy, or an aluminium containing silicon alloy or an aluminium containing compound or mixtures thereof are added to the reactor in an amount between 0.01 and 1% by weight calculated as aluminium based on the weight of silicon supplied to the reactor.
