  • Cupreous catalyst and process for making same
    Patent number: 4503165
    Abstract: Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of a hydroxide of Period IV metal having Atomic Number between 24 and 30, e.g. iron III oxide monohydrate. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.
