标题:负载离子液体中的双金属纳米粒子作为多功能催化剂,用于芳香族底物的选择性加氢脱氧
摘要:嵌入酸性负载型离子液相(feru @ Silp + Il-So 3 H)中的双金属铁-钌纳米粒子可作为多功能催化剂,用于芳香族基质中羰基的选择性加氢脱氧.催化剂材料由分子组分系统地组装,以结合酸和金属位点,从而允许c = O键的氢解而无需芳族环的氢化.所得材料对各种取代的芳族酮中的c = O基团催化加氢脱氧为ch 2单元具有很高的活性和稳定性,因此,它是传统的clemmensen和wolff-Kishner还原反应的理想替代品,而该方法需要化学计量比试剂.Feru @ Silp + Il‐so的分子设计3 H材料为多功能催化系统(mm'@ Silp + Il-Func)开辟了通用途径.

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.

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.

标 题:Direct synthesis of alkoxysilanes using copper-aluminum alloy catalysts
发明人：LEWIS KENRICK MARTIN; MEREIGH ABELLARD
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:An improved catalyzed reaction of silicon metal with alcohol is provided for the formation of alkoxysilanes, particularly trialkoxysilanes. The Direct Synthesis reaction of silicon metal and alcohol employs a catalytically effective amount of a copper-aluminum alloy as a catalyst precursor and further benefits from an effective catalyst-promoting amount of a catalyst promoter.
