标 题:Synthesis of Diacids, Dialdehydes, or Diamines from THF-Diols
发明人：STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO
摘要:A simple and elegant chemical process for the synthesis of oxygenated products, such as acids and aldehydes, or other derivative products, such as amines and nitriles, of cyclic bifunctional molecules made from renewable, bio-based sources such as HMF and/or its reduction product, 2,5-bis(hydroxymethyl)-tetrahydrofuran (bHMTHF) is described. In general, the process involves: a) generating a tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) from bHMTHFs using a sulfonate; b) displacing nucleophilically at least a sulfonate leaving group from the tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) to form a THF-dinitrile; and either c) oxidizing the THF-dinitrile with an acid having a pKa of ≦0 to generate a di-acid, or d) reducing partially the THF-dinitrile to generate a di-aldehyde, or e) reducing fully the THF-dinitrile to generate a di-amine.

标 题:Preparation of gold cyanide
发明人：OKINAKA YUTAKA; SMITH LAWRENCE E
权利人:BELL TELEPHONE LABOR INC
摘要:A synthesis of gold (I) cyanide is described which exhibits high yields and does not yield toxic gases (e.g., HCN). Gold (I) cyanide is important as a source of gold for gold plating baths. A synthesis of AuCN that does not involve evolution of toxic gases (e.g., HCN) is highly advantageous because no disposal problem is involved and the procedure is simpler and more straightforward.

摘要:Disclosed is a direct synthesis method of nanostructured catalyst particles on surfaces of various supports. In the disclosed synthesis method of a catalyst structure having a plurality of nanostructured catalyst particles dispersed in a support by a one-step process using a high-temperature high-pressure closed reactor, the one-step process includes supplying the support and a catalyst source into the high-temperature high-pressure closed reactor; supplying an atmosphere forming gas of the reactor into the reactor; perfectly sealing the high-temperature high-pressure closed reactor and heating the reactor to produce the catalyst structure in the reactor under self-generated pressure and synthesis temperature conditions, the catalyst structure including the plurality of nanostructured catalyst particles dispersed in the support; removing internal gases of the reactor to allow the reactor to be in a high-temperature, atmospheric pressure state and supplying an inert gas into the reactor to remove unreacted materials and byproducts remaining in the reactor; and cooling the reactor to room temperature while supplying the inert gas to synthesize the catalyst structure.

摘要:A supported composite particle material comprises: a composite particle formed of an oxidized nickel and X (wherein X represents at least one of elements selected from the group consisting of nickel, palladium, platinum, ruthenium, gold, silver and copper); and a support on which the composite particle is supported, the supported composite particle material having a supported layer in which the composite particle is localized.
