标题:Process for the direct synthesis of trialkoxysilane
发明人：LEWIS KENRICK M; MEREIGH ABELLARD T; O'YOUNG CHI-LIN; CAMERON RUDOLPH A
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:The Direct Synthesis of trialkoxysilane is carried out by conducting the Direct Synthesis reaction of silicon and alcohol, optionally in solvent, in the presence of a catalytically effective amount of Direct Synthesis catalyst and an effective catalyst-promoting amount of Direct Synthesis catalyst promoter, said promoter being an organic or inorganic compound possessing at least one phosphorus-oxygen bond.

摘要:Disclosed is a process in which surface-active additives are used in the slurry phase Direct Synthesis of trialkoxysilanes to shorten the period between the start of the reaction and the attainment of steady-state rates and selectivities, to improve product yields and to control or prevent foam formation. Compositions comprising silicone antifoam compounds and fluorosilicone polymers are the preferred surface-active additives of the instant process.

标题 :Nanosized copper catalyst precursors for the direct synthesis of trialkoxysilanes
发明人：LEWIS KENRICK M; ENG REGINA NELSON; CROMER SABRINA R; MEREIGH ABELLARD T; O'YOUNG CHI-LIN
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要: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 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.

发明人：LEWIS KENRICK M; YU HUA
权利人:OSI SPECIALTIES INC
摘要:Disclosed is an improved process for the slurry phase Direct Synthesis of trialkoxysilanes which comprises the activation of copper catalyst and silicon with a reducing agent such as hydrogen gas, carbon monoxide or monosilane. Such activation affords high, stable reaction rates and selectivities and high silicon overall conversion especially in alkylated benzene solvents.

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.
