Zusammenfassung:	The invention relates to a process for producing acrylonitrile by ammoxydation of propylene, which comprises the use of a fluidized bed catalyst whose composition is represented by the empiric formula (FeSb a)b Mo 10 Bi c Fe d K k M m N n G g Q q R r T t O x (SiO2)y where (FeSb a) represents iron and stibium forming iron stibnate, the ratio Mo/Me ranges between 0.8 and 1 and the ammoxidation reaction is performed while adding molybdenum-containing material to the reaction mixture. Invenţia se referă la un procedeu pentru producerea acrilonitrilului prin amoxidarea propilenei, care cuprinde utilizarea unui catalizator în strat fluidizat, care are o compoziţie reprezentată prin formula empirică (FeSba)bMo10BicFedKkMmNnGgQqRrTtOx(SiO2)yîn care (FeSba) reprezintă fier ?i antimoniu formând antimoniat de fier, raportul Mo/Me este cuprins între 0,8 ?i 1, ?i în care reacţia de amoxidare este efectuată cu adăugarela amestecul de reacţie, de material conţinândmolibden.
