Preparation of catalytic copper and production of organochlorosilane using said copper

摘要

In the preparation of catalytic copper with an average particle size between about 0.1 and 100 microns and a copper-I oxide content of about 3 to 100% by oxidation of a Cu powder, the improvement which comprises carrying out the oxidation with oxygen at a reduced partial pressure compared with that of air, the resulting catalyst being of enhanced catalytic activity especially for the reaction of hydrocarbon chlorides with silicon for the production of organochlorosilanes (Rochow synthesis) wherein the desired material is produced in higher yield and greater selectivity.
