权利人:FUJIFILM CORP
摘要:A gas separation membrane including a gas separation layer contains a crosslinked polyimide compound. In the gas separation membrane, and a gas separation module, a gas separator, and a gas separation method obtained by using the gas separation membrane, the crosslinked polyimide compound has a specific structural portion. A composition for forming a gas separation layer suitable for forming a gas separation layer of the gas separation membrane; a method of producing a gas separation membrane obtained by using this composition; a polyimide compound suitable as a raw material of a gas separation layer of the gas separation membrane; and a diamine monomer suitable for synthesis of this polyimide compound are provided.

权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a metal-treated chemically-modified solid oxide such as a sulfur oxoacid anion-modified solid oxide, a phosphorus oxoacid anion-modified solid oxide, or a halide ion-modified solid oxide, to provide a reaction mixture; and (2) applying reaction conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or the salt thereof. Methods of regenerating the metal-treated chemically-modified solid oxide are described.

发明人：LASSEN KENNETH M
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:The present invention discloses processes for producing γ-dicarbonyl compounds by contacting an aldehyde compound, an α,β-unsaturated carbonyl compound, and a catalyst composition in the presence of an amide diluent. The resultant γ-dicarbonyl compounds then can be used to synthesize pyrrole compounds, such as 2,5-dimethylpyrrole.
