Preparation Of Nanosized Copper And Copper Compounds

US Patent:
7087100, Aug 8, 2006
Filed:
Oct 9, 2001
Appl. No.:
09/974503
Inventors:
Kenrick M. Lewis - Rego Park NY, US
Hua Yu - White Plains NY, US
Regina Nelson Eng - Pike Road AL, US
Sabrina R. Cromer - Mount Vernon NY, US
Chi-Lin O'Young - Poughkeepsie NY, US
Abellard T. Mereigh - Yonkers NY, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
B22F 9/30
C22B 15/00
C22B 23/00
C22B 25/00
US Classification:
75362, 423604, 423618, 42359418, 977DIG 1
Abstract:
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.

Rochow-Müller Direct Synthesis Using Nanosized Copper Catalyst Precursors

US Patent:
7153991, Dec 26, 2006
Filed:
Oct 9, 2001
Appl. No.:
09/974266
Inventors:
Kenrick M. Lewis - Rego Park NY, US
James S. Ritscher - Marietta OH, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
C07F 2/16
US Classification:
556472, 556466
Abstract:
A Direct Synthesis of making organohalosilanes with greater selectivity to the dialkyldihalosilane is disclosed herein. By using nanosized copper catalyst precursors, and preferably nanosized promoters as well, D/T values of greater than 10, and preferably greater than 15, are obtainable with silicon conversions in excess of 80 wt. %. Shorter induction times are realized using the nanosized copper catalysts in the Direct Synthesis. The nanosized copper catalyst precursors most preferably have an average particle size of less than 100 nanometers.

Nanosized Copper Catalyst Precursors For The Direct Synthesis Of Trialkoxysilanes

US Patent:
7339068, Mar 4, 2008
Filed:
Oct 9, 2001
Appl. No.:
09/974092
Inventors:
Kenrick M. Lewis - Rego Park NY, US
Regina Nelson Eng - Pike Road AL, US
Sabrina R. Cromer - Mount Vernon NY, US
Abellard T. Mereigh - Yonkers NY, US
Chi-Lin O'Young - Poughkeepsie NY, US
Assignee:
Momentive Performance Materials Inc. - Wilton CT
International Classification:
C07F 7/04
US Classification:
556465, 556400, 556466, 556470
Abstract:
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)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 600 nanometers, preferably from about 0. 1 to about 500 nanometers, and most preferably from about 0. 1 to about 100 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.
