Problems solved by technology

However, a catalyst in a slurry form has problems about safety, an increase in wastes, operability, productivity and so on.
For example, one of the problems is a problem that many catalysts are naturally ignitable, thereby causing an anxiety about safety.
A second one thereof is a problem that the catalyst generally needs to be removed by filtration in order to collect a reaction product, thereby making facilities therefor and the operation thereof complicated.

Production of a Film-formed Catalyst

[0051] A film-formed catalyst made of a three-component copper-nickel-ruthenium catalyst active material and carried on synthetic zeolite was prepared as follows.

[0052] Synthetic zeolite was charged into a flask having a volume of 1 L, and subsequently thereinto was put a solution wherein copper nitrate, nickel nitrate and ruthenium chloride were dissolved in water in such a manner that the ratio by mole between the metal atoms therein would satisfy: Cu:Ni:Ru=4:1:0.01. While the solution was stirred, the temperature thereof was raised. An aqueous 10% by weight Na2Co3 solution was dropwise added slowly at 90° C. to the solution while the pH thereof was controlled into the range of 9 to 10. The solution was ripened for 1 hour, and subsequently the resultant precipitation was filtrated, washed with water, dried at 80° C. for 10 hours, and then calcined at 600° C. for 3 hours to yield a powdery catalyst active material. The ratio of metal oxides in ...

example 1

[0054] The reaction apparatus illustrated in FIG. 3 was used to conduct the following reaction.

[0055] A part of the film-formed catalyst obtained in Production Example 1 were folded into waved plates, and the wave plates and the remaining flat plates were alternately wounded in layers and arranged into the form of a doughnut having an inside diameter of 80 mm and an outside diameter equal to the inside diameter (inside diameter: 130 mm) of the 2-L separable flask 2 made of glass. The volume of the region 3 into which the film-formed catalyst was fitted was 660 mL. The film-formed catalyst was thus formed to have plural channels being continuous through the axial direction of the separable flask 2. Each channel had a cross-section area of about 0.1 cm2. Into the separable flask 2 was charged 1200 g of dodecyl alcohol (Kalcol-2098, manufactured by Kao Corp.), and then hydrogen gas was blown in at a rate of 20 L / h, the rate being calculated in terms of the standard state volume thereo...

Abstract

The present invention provides a reaction apparatus which is used for gas-liquid chemical reaction and is capable of producing a target reaction product. The present invention provide a reaction apparatus for conducting a gas-liquid chemical reaction in the 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; and a process for producing a tertiary amine. This reaction apparatus is preferably used to react a primary or secondary amine with an alcohol.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a reaction apparatus wherein a film-formed catalyst is used to conduct a gas-liquid chemical reaction in the state that a liquid is in a continuous phase, in particular, a reaction apparatus which is suitably used when an alcohol and a primary or secondary amine are used as starting materials to produce the corresponding tertiary amine. BACKGROUND OF THE INVENTION [0002] A great number of industrial reactions are conducted in mixing-chamber type reaction apparatus wherein a solid catalyst is made into a slurry and used. The catalyst made into the slurry is made of fine powder. In the presence of the catalyst, a reactive gas such as hydrogen or ammonia is brought into contact with a liquid to conduct reaction. When the reaction ends, the catalyst is generally removed by filtration, so as to collect the reaction product. [0003] However, a catalyst in a slurry form has problems about safety, an increase in wastes, operabili...
