Patent number: 8513449Abstract: The present invention provides a process for using nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and mixtures thereof, as sources of catalytic copper in the Direct Synthesis of trialkoxysilanes of the formula HSi(OR)3 wherein R is an alkyl group containing from 1 to 6 carbon atoms inclusive. The nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and their mixtures of this invention have average particle sizes that are in the range from about 0.1 to about 60 nanometers, preferably from about 0.1 to about 30 nanometers, and most preferably from about 0.1 to about 15 nanometers. Nanosized sources of catalytic copper afford high dispersion of catalytic sites on silicon and contribute to high reaction rates, high selectivity and high silicon conversion. The nanosized copper catalyst precursors of the invention permit the use of substantially reduced levels of copper compared to conventional practice.Type: GrantFiled: November 19, 2010Date of Patent: August 20, 2013Assignee: Momentive Performance Materials, Inc.Inventors: Sabrina R.

Patent number: 7087100Abstract: The present invention is a process for producing nanosized metal compounds. The preferred product is nanosized copper, nanosized copper (I) oxide, and nanosized copper (II) oxide. The process includes heating a copper metal precursor in a hydrocarbon preferably selected from alkylated benzenes, polyaromatic hydrocarbons, paraffins and/or naphthenic hydrocarbons. The heating is desirably at a temperature and time effective to convert, for example, the copper metal precursor to nanosized copper (II) oxide, nanosized copper (I) oxide and/or nanosized copper metal. Separation of the hydrocarbon is then performed. Recovering the solid product and recycle/reuse of the recovered hydrocarbon in subsequent preparations of nanosized metal and metal oxides may be performed. The nanosized metal oxides of the invention may additionally be converted to nanosized metal salts by reaction with the appropriate acids while dispersed in the hydrocarbons.Type: GrantFiled: October 9, 2001Date of Patent: August 8, 2006Assignee: General Electric CompanyInventors: Kenrick M.
