Abstract

DISCLOSED IS AN AMMOXIDATION CATALYST COMPOSITION FOR USE IN PRODUCING ACRYLONITRILE FROM PROPYLENE, OR METHACRYLONITRILE FROM ISOBUTENE OR TERT-BUTANOL, BY AMMOXIDATION OF THE PROPYLENE OR OF THE ISOBUTENE ORTERT-BUTANOL, COMPRISING AN OXIDE CATALYST COMPOSITION REPRESENTED BY THE FORMULA:MO12(BI1-AAA)BFECNIDXEYFOG WHEREIN A IS AT LEAST ONE RARE EARTH ELEMENT, X IS AT LEAST ONE ELEMENT SELECTED FROM MAGNESIUM AND ZINC, Y IS AT LEAST ONE ELEMENT SELECTED FROM POTASSIUM, RUBIDIUM AND CESIUM, A IS A NUMBER OF, FROM 0. 6 TO 0. 8, B IS A NUMBER OF FR.OM 0. 5 TO 2, C IS A NUMBER OF FROM 0.1 TO 3, D IS A NUMBER OFFROM 4 TO 10, E IS A NUMBER OF FROM 0 TO 3, F IS A NUMBER OF FROM 0.01 TO 2, AND G IS A NUMBER DETERMINED BY THE VALENCE REQUIREMENTS OF THE OTHER ELEMENTS PRESENT. BY USE OF THE AMMOXIDATION CATALYST COMPOSITION OF THE PRESENT INVENTION, NOT ONLY CAN ACRYLONITRILE AND METHACRYLONITRILE BE PRODUCED IN HIGH YIELD, BUT ALSO A LOWERING OF THE YIELD OF ACRYLONITRILE OR METHACRYLONITRILE CAN BE EFFECTIVELY SUPPRESSED EVEN AFTER THE OPERATION OF THE PRODUCTION PROCESS HAS BEEN CONDUCTED FOR A PROLONGED PERIOD OF TIME.
