  • Catalysts for the production of methylchlorosilanes using zinc oxide promoters
    Patent number: 7323583
    Abstract: The present invention provides a catalyst that may be used to facilitate the formation of dimethylchlorosilanes. A catalyst in which copper oxide and zinc oxide are in intimate contact and form agglomerated particles allows for the increased selectively of the production of dimethylchlorosilanes.

  • Process for treating methylchlorosilanes by-products
    Patent number: 5876609
    Abstract: The instant invention relates to a novel process for the hydrolysis of the by-products produced during the manufacture of methyldichlorosilanes comprising combining the by-products with an aqueous medium, optionally comprising a surfactant, at a pH range of at least about 7 and at a temperature of above about 0.degree. C. to produce a solid material in which copper and other metals are retained in a solid phase thereby resulting in a product with a high copper content.
