Silver is used as a base material on which doping is done with the transition metals selected from Cu, Co, Mn, Fe, and Ni.
专利号:US-4523022-A 优先权日:1983-07-07 标 题:Analogs of the antibiotic spectinomycin 发明人:THOMAS RICHARD C 权利人:UPJOHN CO 摘要:The present invention concerns the novel, sugar-ring expansion for synthesis of novel analogs of spectinomycin or C-6' analogs of spectinomycin from known aminomethyldihydrospectinomycin and analogs thereof. Additionally, the invention concerns the novel synthesis of novel 7 membered sugar-ring analogs of dihydrospectinomycin and C-6' analogs thereof from novel 7 membered sugar-ring spectinomycin and C-6' analogs thereof by treatment with NaBH4.
专利号:US-9822053-B2 优先权日:2016-01-28 标题:Single step conversion of N-butyraldehyde to 2-ethylhexanal 发明人:BOPPANA Venkata Bharat; HAMPTON JR KENNETH WAYNE; LIU ZHUFANG; SUMNER JR CHARLES EDWAN; TUSTIN GERALD C; STEINMETZ GUY RALPH; STEFFEY MELISSA PAGE 权利人:EASTMAN CHEM CO 摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

专利号:US-6413669-B1 优先权日:1999-06-03 标题 :Melt impregnation of mixed metal oxide 发明人:TAKEUCHI ESTHER S; LEISING RANDOLPH A 权利人:GREATBATCH W LTD 摘要:The present invention is directed to a process for preparing a cathode active material consisting of a single phase of mixed metal oxide, such as a single phase silver vanadium oxide. The synthesis technique involves first heating the starting materials to melt a decomposable starting constituent. This first heating temperature is held for a period of time sufficient to enable the decomposable starting constituent to melt and completely flow throughout and within the other starting materials. Then, the thusly produced melt impregnated reaction admixture is preferably ground to ensure complete homogeneity of the starting materials, followed by heating to the decomposition temperature of the decomposable starting constituent. To finish the synthesis, the decomposed admixture is heated to an elevated temperature above the decomposition temperature to provide the single phase mixed metal oxide.
