    摘要: A process for the production of 3-aminocrotononitrile by dimerization of acetonitrile. In this process, the deprotonation step takes place with sodium amide as a strong base in the presence of liquid ammonia. 3-Aminocrotononitrile is used as an initial product for the production of pharmaceutical agents, pesticides or azo dyes.
