    • The present invention relates to a process for producing a tertiary amine in the presence of a catalyst containing copper and at least one element selected from the group consisting of elements belonging to Groups 2, 3, 7 and 12 of the Periodic Table (long form of the periodic table), said process including the steps of (a) reducing an amide compound in a hydrogen atmosphere; and (b) introducing a dialkyl amine containing a linear or branched alkyl group having 1 to 6 carbon atoms into a reaction product obtained in the step (a), and treating the reaction product with the dialkyl amine. The present invention provides a process for producing high-purity aliphatic tertiary amines containing a less amount of by-products by reducing aliphatic acid amides under moderate conditions using a chromium-free catalyst, as well as a process for producing amine derivatives such as amine oxide by using the aliphatic tertiary amines, with a good productivity in an economical manner.
    • 本发明涉及在含有铜的催化剂和选自元素周期表第2,3,7和12族元素中的至少一种元素的存在下制备叔胺的方法(长形式 所述方法包括以下步骤:(a)在氢气氛中还原酰胺化合物; 和(b)将含有具有1至6个碳原子的直链或支链烷基的二烷基胺引入步骤(a)中获得的反应产物中,并用二烷基胺处理反应产物。 本发明提供了一种通过使用无铬催化剂在中等条件下还原脂肪酸酰胺以及生产胺衍生物如氧化胺的方法来生产含有少量副产物的高纯度脂族叔胺的方法 通过使用脂肪族叔胺,以经济的方式具有良好的生产率。
