The present invention provides a method for producing a tertiary amine by using a secondary amine and an alcohol as starting materials to obtain a corresponding tertiary amine. The method of the present invention includes reacting a secondary amine with an alcohol in the presence of a catalyst, wherein the catalyst is previously used in the reaction of a primary amine with an alcohol to obtain a tertiary amine.

Method for producing tertiary amine

A reaction apparatus which is used for conducting a gas-liquid chemical reaction in a state that a liquid is in a continuous phase, wherein its reactor has therein a shear type stirring impeller for dispersing a raw reaction gas or a carrier gas and a film-formed catalyst, which apparatus is capable of producing a target reaction product; and a process for producing a tertiary amine in such reaction apparatus.

Reaction apparatus

The invention provides a method of using an alcohol and a primary or secondary amine as the starting material to produce the corresponding secondary amine easily at a high yield and a catalyst used therein. The invention relates to a film-type catalyst for production of a tertiary amine, which is used in producing a tertiary amine from an alcohol and a primary or secondary amine as the starting material, and a process for producing a tertiary amine, which includes reacting an alcohol with a primary or secondary amine in the presence of the film-type catalyst.

Process for producing tertiary amine

Disclosed is a process for producing a tertiary amine from a primary or secondary amine and alcohol as corresponding starting materials, which includes step (i) of dehydrogenating an alcohol to obtain an aldehyde, step (ii) of reacting the aldehyde with a primary or secondary amine to obtain a primary or secondary amine adduct, and step (iii) of hydrogenating the primary or secondary amine adduct to obtain a tertiary amine, wherein step (ii) is carried out independently of the other steps.

The present invention relates to a process for producing a tertiary amine from its corresponding primary or secondary amine and alcohol as the raw materials by using a film type catalyst. Disclosed is a process for producing a tertiary amine from an alcohol and a primary or secondary amine, which including conducting the reaction, while circulating a reaction solution at least 3 times/hour in a reactor loaded with a film type catalyst in an external circulating line ancillary to a tank.

Process for production of tertiary amines

The invention relates to a process for producing a tertiary amine, which includes reacting an alcohol with a primary or secondary amine gas in the presence of a catalyst with an agitating vessel under the stirring conditions where the ratio (P/P) of agitating power at the time of the maximum flow rate of an introducing gas (P[W]) to agitating power at the time of no introduction of the gas (P[W]) becomes 10or more wherein Nis the gas flow number, and N=Qg/ndwhereupon Q[m/s] is the flow rate of an introducing gas, n [1/s] is the number of revolutions, and d [m] is the diameter of an agitating impeller.

The invention provides a method for manufacturing a tertiary amine, including reacting a tertiary amine with an alcohol and a primary or secondary amine in a reactor loaded with a film type catalyst, controlling the superficial velocity of liquid in the reactor at 0.1 cm/s or more.

Method for manufacturing tertiary amine

The invention provides a film-type dehydrogenation reaction catalyst for aldehyde production, which is used in producing an aldehyde from an alcohol as a starting material, as well as a process for producing an aldehyde, which includes reacting an alcohol in the presence of the film-type dehydrogenation reaction catalyst.

Process for producing aldehyde

The present invention relates to a process for producing an anode for a secondary battery, which is capable to reduce a contact resistance between a sintered material which contains silicon as an anode active material and a current collector. A binder and a solvent are mixed with a silicon-containing anode material to prepare a slurry. A base material made of a foil or mesh of conductive metal is coated with the slurry, and the solvent is removed to form a coated film. The coated film is sintered in a non-oxidizing atmosphere, thereby integrating a sintered material of the coated film with the base material.

Method of manufacturing secondary battery negative electrode

The present invention relates to a lithium secondary battery with a cathode and an anode, each electrode containing an active material capable of incorporating and releasing lithium ions. The anode includes a sintered material which contains 50 to 99 % by weight of silicon and 1 to 50% by weight of carbon material, and has an electrical conductivity not less than 1 S/cm. By employing the anode including the sintered material containing silicon as the anode active material and carbon material, an increased packing density of the active material and an increased capacity per volume can be obtained. Furthermore, the anode conductivity of not less than 1S/cm can provide a high capacity and improved cycle property.
