(57) [Summary] [Structure] An ammoxidation catalyst composition having an atomic ratio represented by the general formula: Mo 12 Bia Ceb Fec Znd Xe Yf Zg Ah Oi, and a method for producing acrylonitrile or methacrylonitrile using the same. . [Effect] Propylene, isobutene or tertiary butano- In the process of producing acrylonitrile or methacrylonitrile in the ammoxidation reaction of ethylene, By-products of acrolein or methacrolein, which cause clogging, scale, and COD in wastewater, can be suppressed. |
