Acrylonitrile was manufd. by gas-phase ammoxidn. of propylene-NH3-O(I) at 380-500≦̸C with a fluidized bed catalyst contg. 10:x:0.1-2.5:0.05-1:0.2-5:y:0-3 Fe Sb Mo X Te Y Na-oxide(X=V,W; Y=Cu, Mg, Zn, Ni; X=13-28; Y=0-4 for X=13-20 or y=2-6 for X=20-8) on 20-200mol SiO2. Thus, 20% silica sol. contg. 0.03% Na2O was treated syccessively with NH4molybdate, NH4tungstate, and Te(OH)6 in H2O, and Sb2O3, adjusted to pH 2 with NH4OH, and heated 8hr at 100≦̸C. The slurry-was spray-dried and heated at 740≦̸C for 4hr to give a 10:20:0.8:0.2:1.7 2.5:0.15:64:50 Fe-Su-Mo-W-Te-Cu-Na-O-SiO2 catalyst.
