Reaction apparatus

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.

1 . A reaction apparatus for conducting a gas-liquid chemical reaction in the state that the liquid forms a continuous phase, provided with a film-formed catalyst and a shear type stirring impeller for dispersing a raw reaction gas or a carrier gas.  
     
     
         2 . The reaction apparatus according to  claim 1 , wherein the shear type stirring impeller is a concave turbine or an edged turbine.  
     
     
         3 . The reaction apparatus according to  claim 1  or  2 , wherein the reactor has therein an inducement baffle for the raw reaction gas.  
     
     
         4 . The reaction apparatus according to  claim 1  or  2 , wherein the gas-liquid reaction is a reaction for producing a tertiary amine from a primary or secondary amine and an alcohol.  
     
     
         5 . A process for producing a tertiary amine, comprising the step of reacting a primary or secondary amine with an alcohol, in a reaction apparatus provided with a shear type stirring impeller, by conducting a gas-liquid chemical reaction with a film-formed catalyst in the state that the liquid forms a continuous phase, dispersing a raw reaction gas or a carrier gas with the impeller.  
     
     
         6 . The process for producing a tertiary amine according to  claim 5 , wherein the alcohol is a linear or branched, saturated or unsaturated aliphatic alcohol having 6 to 36 carbon atoms.  
     
     
         7 . The process for producing a tertiary amine according to  claim 5  or  6 , wherein the primary or secondary amine is a primary or secondary aliphatic amine to react with an alcohol.
