    摘要: A silicone containing automotive vinyl, rubber and leather protectant in the form of a solvent solution, a water dilutable emulsion or as a "neat" fluid. The silicone is an alkylaryl silicone copolymer having long chain hydrocarbon units and aromatic units. The protectant formulation exhibits greater substantivity to organic surfaces such as vinyl, rubber and leather and possesses enhanced penetration of organic surfaces to which it is applied resulting in an improvement in protection of such surfaces against the deterioration caused by ultraviolet radiation. Treated surfaces are also rendered paintable.

    摘要: The present invention is a process for the production of selected methoxysilanes in high yield. The process involves reacting methanol with a silazane at a temperature greater than the boiling point of product methoxysilane and less than the temperature of methanol. Under these temperature conditions rapid removal of product methoxysilanes from the reaction mixture occurs minimizing undesirable reactions which can reduce yield of the process. The described process has been found useful for the production of dimethylmethoxysilane, dimethyldimethoxysilane and methyldimethoxysilane.
