摘要:
Provided is a method for producing a 2-alkenylamine compound efficiently and at low cost, using a primary or secondary amine compound and a 2-alkenyl compound as the starting materials therefor. The 2-alkenylamine compound is produced by adding Bronsted acid when 2-alkenylating by reacting the primary or secondary amine compound with the 2-alkenyl compound, and 2-alkenylating in the presence of a catalyst comprising a complexing agent and a transition metal precursor stabilized by a monovalent anionic five-membered conjugated diene.
摘要:
The present invention provides a porous metal-containing carbon-based material that is stable at high temperatures under aqueous conditions. The porous metal-containing carbon-based materials are particularly useful in catalytic applications. Also provided, are methods for making and using porous shaped metal-carbon products prepared from these materials.
摘要:
The present invention relates to a process for producing a tertiary amine, including the following steps (1) and (2): Step (1): introducing an alcohol having 1 to 36 carbon atoms and a raw amine represented by the following general formula (I) into a first reaction vessel to react with each other in the presence of a catalyst and hydrogen, and then continuing the reaction while discharging water produced in the reaction and a hydrogen-containing gas out of a reaction system in the first reaction vessel: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 R 2 NH€ƒ€ƒ€ƒ€ƒ€ƒ(I) wherein R 1 and R 2 are each independently a hydrogen atom or a hydrocarbon group having 1 to 36 carbon atoms; and Step (2): introducing the hydrogen-containing gas discharged from the first reaction vessel into a second reaction vessel to reduce an amount of carbon monoxide contained in the hydrogen-containing gas, and then introducing a part or whole of the hydrogen-containing gas into the first reaction vessel.
