Class Information
Number: 558/459
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Nitriles (i.e., compounds having cyano bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon) > Acyclic (e.g., purification of saturated nitriles, etc.) > Nitrogen attached indirectly to the cyano group by nonionic bonding > Hydrogenation of dinitriles, or displacement of halo, hydroxy, or alkoxy by ammonia or substituted ammonia
Description: Processes under sublcass 452 wherein halo, hydroxy or alkoxy is displace by ammonia or substituted ammonia, or wherein a dinitrile is hydrogenated.
