20110207962 - Production method of methionine: The present invention aims to provide a method of producing methionine by hydrolyzing M-hydantoin in the presence of a basic potassium compound, which can effectively prevent corrosion of reaction vessels in both the liquid phase and gaseous phase of a hydrolysis solution even at a higher temperature, and enables a... Agent: Sumitomo Chemical Company, Limited

20110201841 - Oxidative mono-halogenation of methane: Oxidatively halogenate methane by placing a feedstream that comprises methane, a source of halogen, a source of oxygen and, optionally, a source of diluent gas in contact with a first catalyst (e.g. a solid super acid or a solid super base) that has greater selectivity to methyl halide and carbon... Agent:

20110201842 - Method for recovering carboxylic acids from dilute aqueous streams: Improvement in separating lower carboxylic acids from aqueous streams via liquid-liquid extraction with pressurized liquefied propylene and/or propane, wherein carboxylic acid is transferred from the aqueous phase into the liquid solvent phase (extract).... Agent: Arkema Inc.

20110196171 - Process for producing hydrogenated aromatic polycarboxylic acid: A production method of a hydrogenated product of aromatic polycarboxylic acid by the hydrogenation of aromatic ring of the aromatic polycarboxylic acid in the presence of a catalyst composed of rhodium in combination with palladium and/or platinum supported on a carbon support. By using the catalyst, the hydrogenated product of... Agent: Mitsubishi Gas Chemical Company, Inc.
