METHOD OF PRODUCTION OF CONTACT MASS Russian patent published in 2005 - IPC

Abstract RU 2265073 C2

FIELD: production of contact mass for reaction of powder silicon, alkyl halide and copper catalyst.

SUBSTANCE: proposed method includes forming mass by mixing silicon and copper source, heating to temperature of about 500°C and subjecting to heat treatment at temperature above 500°C where said heat treatment increases content of copper source Cu₃Si in contact mass. Contact mass thus obtained is used as catalyst in production of alkylhalosilane including reaction between alkyl halide and silicon in presence of contact mass.

EFFECT: enhanced efficiency and selectivity.
