Abstract

An improved process for the preparation of acrylonitrile by the reaction of propylene, ammonia and oxygen in a fluidized catalyst bed in which the propylene and ammonia are premixed and fed in downwardly streams that are directly aligned with upwardly directed streams of an oxygen containing gas under conditions such that there is complete mixing of the gas streams prior to the gases having significant contact with the catalyst.
