20060241308 - Probe for measuring phytase activity: P

20060241309 - Method for the production of maleic anhydride: A process for preparing maleic anhydride by oxidizing n-butane in the gas phase under heterogeneous catalysis with oxygen-containing gases over a vanadium-, phosphorus- and oxygen-containing catalyst in a reactor unit at a temperature in the range from 350 to 500° C., removing the maleic anhydride formed to form a gas...

20060241310 - V-p-ci composite oxide catalyst precursor used for producing maleic anhydride from butance: The present invention provides a catalyst precursor for producing maleic anhydride by oxidizing butane. Said catalyst precursor is prepared by a process comprising partially reducing V+5 to V+4 in a mixture of alcohols consisting of isobutanol and benzyl alcohol in a volume ratio of 2.5-5.0, then adding a phosphoric oxy-acid...

20060235231 - Histone deacetylase inhibitors: The present invention provides histone deacetylase inhibitors of general formula (I), process for the preparation of such compounds and uses of the compounds in medicine....

20060235232 - Catalysts for gas phase oxidations: A catalyst for gas-phase oxidations which comprises an inert support and a catalytically active composition comprising transition metal oxides applied thereto, or a precatalyst, is described. The (pre)catalyst is obtained by treating the inert support with an aqueous suspension or solution of the transition metal oxides or their precursor compounds,...

20060235233 - Methods for removing catalyst residue from a depolymerization process stream: The invention relates to methods and systems for selective removal of catalyst residue from a depolymerization product stream without a water quench, as well as methods and systems for subsequent recovery of residual linear oligomer. The substantially metal-free and substantially water-free residual oligomer byproduct can then be advantageously used as...

20060235234 - New route to alpha-tocopherol, alpha-tocopheryl alkanoates and precursors thereof: The present invention is concerned with a novel process for the manufacture of (E/Z)-4-alkanoyloxy-3,5,6-trimethyl-2-phytylphenyl esters and silyl ethers, precursors of α-tocopherol and α-tocopheryl alkanoates, by cross-metathesis reaction of 2-alkenyl-3,5,6-trimethylhydroquinone dialkanoates or 4-alkanoyloxy-2-alkenyl-3,5,6-trimethylphenyl silylethers with 2,6,10,14-tetramethylpentadecene or a phytol derivative, e.g. phytyl acetate, in the presence of a cross-metathesis catalyst. As...

20060229458 - Processes for the preparation of 2-methylfuran and 2-methyltetrahydrofuran: Processes are disclosed for the preparation of 2-methylfuran and 2-methyltetrahydrofuran. The continuous vapor-phase processes are commercially viable and efficient because they permit the preparation of 2-methylfuran and 2-methyltetrahydrofuran using commercially-available catalysts, namely, a reduced copper-based catalyst consisting essentially of cupric oxide, chromium (III) oxide, manganese oxide and barium chromate and...

20060229459 - Crystalline base of citalopram: The present invention relates to the crystalline base of the well known antidepressant drug citalopram, 1-[3-(dimethylamino)propyl]-1-(4-fluorophenyl)-1,3-dihydro-5-isobenzofurancarbonitrile, formulations of said base, a process for the preparation of purified salts of citalopram, such as the hydrobromide, using the base, the salts obtained by said process and formulations containing such salts....

20060229460 - Catalyst preparation: Titanium silicallite crystals useful as catalyst for the production of propylene oxide are prepared by forming a solution of a silicon component, a titanium component and a template, the mol ratio of template to silicon component being 0.25 or less and heating the solution to reaction temperature at a rate...

20060224002 - Chiral di- and triphosphites: The invention claims chiral di- and triphosphites of general formulas (I) or (II), which are bridged by suitable groups. The claimed compounds can be used in asymmetric transition metal catalysis and as chiral transition metal catalysts....
