<P>PROBLEM TO BE SOLVED: To provide a method for producing a tertiary amine selectively with a high yield by a reductive amination reaction in a batch system. <P>SOLUTION: In this method for producing the tertiary amine, an aldehyde expressed by formula R-CHO (in the formula, R shows a 2-20C aliphatic hydrocarbon group, 3-20C alicyclic hydrocarbon group or 6-20C aromatic hydrocarbon group), ammonia and hydrogen are reacted together in a batch system in the presence of a hydrogenation catalyst, to thereby produce the tertiary amine expressed by formula (R-CH<SB POS="POST">2</SB>)<SB POS="POST">3</SB>N (in the formula, R is defined above), wherein a palladium catalyst is used as the hydrogenation catalyst, and the reaction is performed under the condition of a hydrogen pressure of 0.1-6.5 MPa. <P>COPYRIGHT: (C)2012,JPO&INPIT |
