摘要： The present invention is a method for reducing the ionic chloride content of hydroxyl-terminated siloxanes. The method involves contacting the hydroxyl-terminated siloxanes with a molecular sieve effective in removing residual water from the siloxanes. Since ionic chloride strongly partitions into the water phase, ionic chloride is removed along with the water phase. In a preferred embodiment of the present method as aprotic solvent is employed to facilitate water removal from the hydroxyl-terminated siloxanes.

摘要： The instant invention is a method for the quenching of a spent bed resulting from the reaction of organic halides with silicon metal to form organohalosilanes. The method employs a strong base and elevated temperature to digest the hydrophobic siloxane-rich coating and dislodge the carbon coating which forms around the spent bed particles. Removal of these coatings allows more rapid and complete quenching of the autoxidants on the surface of the spent bed particles.

摘要： A process for reducing the chlorocarbon content of alkylsilanes is described. The process comprises (A) contacting crude alkylsilanes, containing as a minor portion chlorocarbons, and a hydrogen-containing silane with a catalyst; wherein the catalyst is a sufficient amount of an effective Lewis acid forming material; (B) facilitating the reaction of the chlorocarbons with the hydrogen-containing silane in contact with the catalyst to convert the chlorocarbons to a linear or branched alkanes; (C) separating catalyst from the alkylsilanes and alkanes; and (D) recovering alkylsilanes with lowered chlorocarbon content.

摘要： Olefinic siloxanes which are inhibitors for platinum catalyst can be made by the reaction of secondary or tertiary acetylenic alcohols with siloxanes having silicon-bonded-hydrogen atoms. These olefinic siloxanes inhibit the platinum catalyst such that it will not catalyze the addition of SiH to aliphatic unsaturation at room temperature and does not inhibit the reaction at elevated temperatures. These olefinic siloxanes contain from 3 to 10 siloxane units with a total of at least three units from at least one RHSiO and/or R.sub.2 HSiO.sub.0..sub.5, at least one ##EQU1## and the remaining siloxane units being ##EQU2##R.sub.3 SiO.sub.0..sub.5, SiO.sub.2 or RSiO.sub.1..sub.5but no more than three units of any one of these siloxane units.

摘要： A process is described by which numerous waste or by-product chlorosilane streams can be treated to obtain a granular gel that is easily handleable in further processing steps, shipment, or disposal operations. By hydrolyzing a combined stream with an average SiCl functionality greater than or equal to 2.8 in an aqueous medium at elevated temperature a granular gel is obtained in all cases. The combined stream can be formed by blending several different streams to obtain the desired average SiCl functionality. If the aqueous medium is concentrated hydrogen chloride, the hydrogen chloride generated in the hydrolysis step can be recovered.

摘要： A redistribution process for enriching a low-boiling methylsilane mixture in a methylchlorosilane selected from a group consisting of dimethylhydrochlorosilane and trimethylchlorosilane. The process comprises contacting a low-boiling methylsilane mixture, resulting from the contact of methyl chloride with silicon, with alumina under non-equilibrium conditions at a temperature greater than about 150.degree. C. The present inventors have discovered that the concentrations of dimethylhydrochlorosilane and trimethylchlorosilane reach maximum levels under non-equilibrium conditions occurring at a temperature greater than about 150.degree. C. The process is also useful for facilitating the removal of olefin and chlorocarbon organic contaminants from the low-boiling methylsilane mixture.
