This invention pertains to an improvement in a process for the formation of secondary or tertiary amines by the catalytic reductive amination of a nitrile with a primary or secondary amine and, particularly to the reductive amination of C8-20 nitriles with a secondary amine. The catalyst employed in the improved reductive amination process is one which has been promoted with a lithium salt or base, e.g., lithium chloride or lithium hydroxide.
本发明涉及通过腈与伯胺或仲胺的催化还原胺化反应生成仲胺或叔胺的工艺的改进,特别是C8-20腈与仲胺的还原胺化反应。在改进的还原胺化工艺中使用的催化剂是用锂盐或碱,如氯化锂或氢氧化锂促进的催化剂。
