DEFINITION

Classification: 558/319

(under subclass 318) Processes wherein there is also utilized

molecular oxygen of a molecular containing gas.

(1) Note. Air is included within the scope of molecular oxygen containing gas.

(2) Note. Ammoxidation is the art term for the type reaction encompassed by this subclass and its indents.

(3) Note. Examples of processes provided for herein are: (a) the production of acrylonitrile by reaction of propane, ammonia and oxygen in the presence of a catalyst, and (b) the production of adiponitrile by reaction of cyclohexane, ammonia and oxygen in the presence of a catalyst.
