Abstract

In an ammoxidation process where reactant gases comprised of a lower alkyl-substituted aromatic hydrocarbon, oxygen, and ammonia are passed over an ammoxidation catalyst in a fixed or fluidized bed system, the improvement of reducing combustion of hydrocarbon and ammonia and achieving a more favorable product distribution by distributing a stream containing reactant oxygen throughout the catalyst bed.
