标题 :Direct synthesis of alkenylhalosilanes
发明人：LEWIS KENRICK MARTIN; ZHU YANJUN; BYRNE CHRISTOPHER M
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

标 题:Rochow-Müller direct synthesis using nanosized copper catalyst precursors
发明人：LEWIS KENRICK M; RITSCHER JAMES S
权利人:GEN ELECTRIC
摘要: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.

标 题 :Combinatorial synthesis of particulate materials
发明人：KODAS TOIVO T; HAMPDEN-SMITH MARK J
摘要:Methods for fabricating and analyzing particulates having a varying material property such that particulates having a selected desirable material property can be identified. The particulates can be analyzed to determine the particulates having the best properties for a particular application. The particulates can be metals, inorganic compounds, organic compounds and composites. The method of the present invention enables the rapid and economical fabrication and screening of a large number of different compositions.

标题:Process for the synthesis of carboxylic anhydrides using a vanadium, phosphorus oxygen containing catalyst composition
发明人：YANG TAI-CHENG; RAO KRISHNA K; HUANG I-DER
权利人:EXXON RESEARCH ENGINEERING CO
摘要:A vanadium, phosphorus oxygen containing catalyst composition capable of partially oxidizing hydrocarbons (e.g., n-butane) to form a carboxylic anhydride (e.g., maleic anhydride), a process for preparing this catalyst, and a process for using this catalyst to form such anhydrides is disclosed. The catalyst composition is prepared by an organic heterogenous technique followed by a water treatment step and activation.
