摘要

A method for the catalytic production of acrylonitrile which consists in contacting, at high temperature, a reactive feed containing propylene, ammonia and molecular oxygen, in gas phase, with a catalyst constituted by an oxide composition of the following empirical formula: Moacobfecxdoe Where x represents at least one atom of an element selected from the group consisting of phosphorus, arsenic, antimony and bismuth; the subscripts a, b, c, d and e indicate respectively the number of the respective atoms of the element being the relation a: b: c: d from 12: 4 to 9: 1 to 5: 0.01 to 0.07 and the subscript e represents the number of oxygen atoms that satisfies the average valence of the elements, the ratio being: e from 12: 39.5 to 52.7.
