摘要:The present invention relates to efficient processes useful in the preparation of fluorinated nucleosides, such as (2S,3R,4S,5R)-5-(2-amino-6-oxo-1,6-dihydro-9H-purin-9-yl)-3-fluoro-4-hydroxy-2-(mercaptomethyl)tetrahydrofuran-3-yl dihydrogen phosphate, also known as 3′-fluoro-thio-guanosine monophosphate or 3′-F-thio-GMP. Such fluorinated nucleosides may be useful as a biologically active compound and or as an intermediate for the synthesis of more complex biologically active compounds. The present invention also encompasses intermediates useful in the disclosed synthetic processes and the methods of their preparation. (I)

摘要:A method is provided for the synthesis of a mesoporous lithium transition metal compound, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product. The mesoporous product can be an oxide, a phosphate, a borate or a silicate and optionally, an additional phosphate, borate or silicate reagent can be added at step (i). The reaction mixture can comprise an optional chelating agent and preferably, the reaction conditions at steps (i) and (ii) are controlled so as to prevent destabilization of the liquid crystal phase. The invention is particularly suitable for producing mesoporous lithium cobalt oxide and lithium iron phosphate. The method can be used to synthesize mesoporous lithium cobalt oxide having a specific surface area in excess of 10 m 2 /g, preferably 15 m 2 /g or more.

标题 :Method for synthesis of reversion resistant chromium bearing wastes and materials

权利人:FORRESTER KEITH EDWARD
摘要:This invention provides a method for stabilization of hexavalent chromium and trivalent chromium bearing wastes, materials, and contaminated soils subject to acid and water leaching tests or leach conditions by addition of water solution, hexavalent chromium reducing agent, precipitating and pH increase agent, and chromium reversion control and stabilizing agents such that leaching of chromium is inhibited to desired levels and resists reversion to hexavalent chromium form over time. The resultant material, contaminated soil and/or waste after stabilization and reversion control is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.

摘要:The present invention relates to a method for preparing an electroactive metal polyanion or a mixed metal polyanion comprising forming a slurry comprising a polymeric material, a solvent, a polyanion source or alkali metal polyanion source and at least one metal ion source; heating said slurry at a temperature and for a time sufficient to remove the solvent and form an essentially dried mixture; and heating said mixture at a temperature and for a time sufficient to produce an electroactive metal polyanion or electroactive mixed metal polyanion. In an alternative embodiment the present invention relates to a method for preparing a metal polyanion or a mixed metal polyanion which comprises mixing a polymeric material with a polyanion source or alternatively an alkali metal polyanion source and a source of at least one metal ion to produce a fine mixture and heating the mixture to a temperature higher than the melting point of the polymeric material, milling the resulting material and then heating the milled material. It is another object of the invention to provide electrochemically active materials produced by said methods. The electrochemically active materials so produced are useful in making electrodes and batteries.

摘要:An electrochemical active material contains a lithiated zirconium, titanium, or mixed titanium/zirconium oxide. The oxide can be represented by the formula LiM'M''XO4, where M' is a transition metal, M'' is an optional three valent non-transition metal, and X is zirconium, titanium, or a combination of the two. Preferably, M' is nickel, cobalt, iron, manganese, vanadium, copper, chromium, molybdenum, niobium, or combinations thereof. The active material provides a useful composite electrode when combined with a polymeric binder and electrically conductive material. The active material can be made into a cathode for use in a secondary electrochemical cell. Rechargeable batteries may be made by connecting a number of such electrochemical cells.
