  • PROCESS FOR PURIFYING AMINOCAPRONITRILE
    Publication number: 20240150278
    Abstract: A process for converting caprolactam to aminocapronitrile (ACN), the process comprising contacting a caprolactam feed stream with ammonia to produce a first crude product stream; separating the first crude product stream to produce an intermediate product stream comprising ACN and caprolactam recovery stream; and purifying the intermediate product stream to produce a purified product stream comprising greater than 95 wt % aminocapronitrile.
