专利号:US-8641798-B2 优先权日:2010-07-13 标 题 :One-step synthesis of monodisperse AU-CU nanocubes 发明人:HIGHT-WALKER ANGELA R; LIU YONGLIN 权利人:HIGHT-WALKER ANGELA R; LIU YONGLIN; US OF AMERICA AS REPRESENTED BY THE SECRETARY OF COMMERCE NIST 摘要:A one-step process for synthesizing gold-copper bimetallic nanocubes. The process comprises the step of simultaneously reducing a copper II salt and a gold halide by 1,2-hexadecanediol in diphenyl ether, and 1-dodecanethiol as well as surfactants 1-adamantanecarboxylic acid and 1-hexadecylamine. The copper II salt may be copper (II) acetylacetonate, copper chloride, copper sulfate, or copper phosphate. The gold halide may be chloroauric acid, gold chloride, gold bromide, or tetrabromoauric acid. The reduction may occur at a temperature between about 160 and 180 degrees Celsius. The copper II salt may be copper (II) acetylacetonate and the gold halide may be chloroauric acid.

The initial growth solution includes a precursor material and a reducing agent in a surfactant solution. Growth of nanostructures in the nanostructure synthesis mixture is monitored during a period of anisotropic growth of the nanostructures to determine a shift from stage II growth of the nanostructures to stage III growth of the nanostructures. The shift from stage II growth to stage III growth is identified, and after identifying the shift, a second growth solution is added to the nanostructure synthesis mixture coincident in time with the shift. The second growth solution includes the precursor material and the reducing agent in the surfactant solution.
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.
