摘要:Provided is a stereoselective synthesis of an intermediate for the preparation of the heterocyclic derivative as a Cap-dependent endonuclease inhibitor. The synthesis process has the advantages of simple operation, higher yield and relatively controllable steroselectivity, such that it is suitable for large-scale production.

标题 :Synthesis of titanium nitride films

权利人:CORNELL RES FOUNDATION INC
摘要:A substantially stoichiometric film of titanium nitride is provided by heating a substrate upon which a solution containing titanium has been applied at a substantially ambient temperature to provide a gel-film containing titanium on the surface of the substrate in an ammonia atmosphere. The substrate is heated to a temperature at which the titanium in the titanium-containing gel-film is substantially completely transformed to a substantially stoichiometric titanium nitride film, and at a rate of temperature change that is great enough to prevent the formation of nonstoichiometric titanium nitride compounds or other undesired titanium compounds in the resulting titanium nitride film. The invention is particularly suited for use in microelectronic devices.

权利人:UNIV BRIGHAM YOUNG
摘要:Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface.

标题 :Production of fischer-tropsch synthesis produced wax
发明人：VAN BERGE PETER JACOBUS; VAN DE LOOSDRECHT JAN; BARRADAS SEAN
权利人:SASOL TECH PTY LTD
摘要:A process for preparing and using a cobalt slurry phase Fischer-Tropsch synthesis catalyst includes introducing a modifying component Mc into a catalyst support precursor, followed by shaping and calcination, to obtain a catalyst support. The catalyst support is impregnated with an aqueous solution of a cobalt salt, to form an impregnated support which is partially dried and calcined, to obtain a catalyst precursor. The catalyst precursor is reduced to form a cobalt slurry phase Fischer-Tropsch synthesis catalyst. A synthesis gas is contacted with this catalyst in a slurry phase Fischer-Tropsch synthesis reaction at elevated temperature and elevated pressure, and a clean wax product that contains less than 50 mass ppm submicron particulates of cobalt is obtained.
