Abstract:
The present invention relates to a process for producing a tertiary amine by reducing an amide compound in the presence of a catalyst containing a sponge copper catalyst obtained by leaching alloy particles containing copper and aluminum and drying the thus leached alloy particles. The present invention provides a process for producing high-purity aliphatic tertiary amines containing a less amount of by-products at a high yield by subjecting aliphatic acid amides to hydrogenation reduction under solvent-free moderate conditions.
Abstract:
The present invention relates to a process for producing an aliphatic amine, comprising the step of contacting a linear or branched, or cyclic aliphatic alcohol having 6 to 22 carbon atoms with ammonia and hydrogen in the presence of a catalyst formed by supporting at least (A) a ruthenium component produced by hydrolysis of a ruthenium compound on a carrier, or by further supporting, in addition to the component (A), a specific second metal component or a specific third metal component on the carrier. According to the process of the present invention, an aliphatic primary amine can be produced from an aliphatic alcohol with a high catalytic activity and a high selectivity.
Abstract:
The present invention provides the early strengthening agent for hydraulic composition, containing a specified compound (1), such as glycerol and at least one inorganic salt A selected from alkali metal sulfates and alkali metal thiosulfates, wherein a molar ratio of compound (1) to the inorganic salt A, compound (1)/inorganic salt A, is 5/95 to 45/55.
Abstract:
The present invention provides a process for producing high-purity aliphatic tertiary amines containing a less amount of by-products by subjecting aliphatic acid amides to hydrogenation reduction under moderate conditions, as well as a process for producing amine derivatives from the aliphatic tertiary amines, with a good productivity in an economically advantageous manner. The present invention relates to a process for producing an aliphatic tertiary amine by subjecting a specific aliphatic amide to hydrogenation reduction in the presence of a catalyst containing copper and at least one element selected from the group consisting of elements belonging to Groups 2, 3 and 7 of the Periodic Table; the catalyst; and a process for producing amine oxide by reacting the tertiary amide obtained by the above production process with hydrogen peroxide.
