Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a tertiary amine by allowing nitrile to react with a secondary amine in the presence of a specific palladium catalyst that is improved in its long-term stability and its operation hours. SOLUTION: A nitrile represented by formula I (R and R are each an alkyl, a cycloalkyl, an aryl, an aralkyl; X is an alkyl, a cycloalkyl, amino, hydroxyl; (n) is 1-4; (m) is 1-2), a secondary amine of formula II and hydrogen are allowed to react to one another at 50-250 deg.C under a pressure of 5-350 bar, thus giving the objective amine of formula III. At this time, it is preferable to use a supported palladium catalyst that has 0.1-10 wt.% of Pd, 0.01-10 wt.% of at least one of other metals selected from the group consisting of metals of the group IB, group VIII of the periodic table, cerium, and lanthanum on the support on the basis of the whole catalyst weight. |
