Abstract
An improvement in process for making cupreous catalyst composition, wherein a copper oxide-preponderant grind charge derived from the oxidation of elemental copper and/or an alloy thereof is subject to high energy milling with concomitant crystal lattice distortion until the average particle of the resulting grind is no larger than about 20 microns, comprises establishing a tin concentration between about 400 and about 3000 ppm in said composition prior to or after said high energy milling. The resulting catalyst is useful for producing organohalosilane from alkyl chloride and silicon.
