A process for selectively hydrogenating a dinitrile to an aminonitrile is provided. The process comprises contacting a dinitrile with a hydrogen-containing fluid in the presence of a solvent comprising an alcohol or liquid ammonia, at least one metal catalyst, and a carbonyl group-containing additive such as, for example, organic amides, organic esters, salts of carboxylic acids, or urea.
本发明提供了一种将二腈选择性氢化为氨基腈的工艺。该工艺包括在包含醇或液氨的溶剂、至少一种金属催化剂和含羰基的添加剂(例如有机酰胺、有机酯、羧酸盐或尿素)的存在下,使二腈与含氢流体接触。
