Abstract
A method is provided for improving alkylhalosilane selectivity in the direct method for making alkylhalosilane. There is introduced into the alkylhalosilane reactor, an effective amount of an organophosphine, such as trimethylphosphine, to enhance the formation of dialkylhalosilane during the direct reaction of alkylhalide and particulated silicon-copper contact mass.
