DEFINITION

Classification: 558/315

(under subclass 308) Processes wherein there is employed as a reactant an aldehyde, a ketone, or a compound having nitrogen double bonded to carbon.

(1) Note. Examples of processes provided for herein are: (a) the production of acetonitrile and acrylonitrile by reacting acrolein with ammonia and oxygen in the presence of an ammoxidation catalyst, and (b) the production of a

saturated aliphatic nitrile from an unsaturated aliphatic primary imine by reacting the imine with excess ammonia in the presence of a dehydrogenation-hydrogenation catalyst.
