Abstract:
1. A process for producing a tertiary amine, which comprises 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 g /P 0 ) of agitating power at the time of the maximum flow rate of an introducing gas (P g [W]) to agitating power at the time of no introduction of the gas (P 0 [W]) becomes 10 −1.8Na or more wherein N a is the gas flow number, and Na=Q g /nd 3 whereupon Q g [m 3 /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, wherein the agitation is carried out with a shear-force agitating impeller, and wherein the catalyst comprises a metal which is Cu alone or combined with at least one transition metal element.
