Acrylonitrile was produced in pilot plant from propylene, ammonia, and atmospheric oxygen in a fixed‐bed reactor in the presence of Bi/Mo/Si oxide shell catalyst. The propylene conversion, which can amount to about 70% under optimal conditions, was studied as a function of structural properties and the chemical composition of the catalyst, and of the composition of the starting mixture. Acrylonitrile of adequate purity for use in polymerizations could be obtained by multi‐stage processing of the crude product.
