Abstract: The application relates to a method for preparing organohalosilanes in a two-step process: Steps (i) contacting a copper catalyst with hydrogen gas and halogenated silanes forming a silicon-containing copper catalyst; and Step (ii) contacting said silicon-containing copper catalyst with an organohalide to form the organohalosilane.
Abstract: A method of preparing a silicone resin, the method comprising reacting at least one halodisilane and, optionally, at least one halosilane with at least one alcohol in the presence of an organic solvent to produce an alcoholysis product; reacting the alcoholysis product with water to produce a hydrolyzate; and heating the hydrolyzate to produce the resin.
