ABSTRACT:
A method for controlling the direct process to vary the concentrations of trialkylhalosilanes and alkyltrihalosilanes in the product. The method comprises contacting an alkyl chloride with silicon metalloid in the presence of a catalytic amount of a catalyst comprising 0.5 to 10 weight percent copper, 5 to 200 ppm tin, 25 to 2,500 ppm phosphorous, and greater than zero to less than 50 ppm zinc, where the concentration of each of the catalyst components is based on the weight of the silicon, at a temperature within a range of about 250.degree. C. to 400.degree. C. The present inventors have found that by controlling the zinc concentration the concentrations of trialkylhalosilanes and alkyltrihalosilanes in the product can be varied.
