An object of the present invention is to provide an improved method and catalyst for ammoxidizing propylene to acrylonitrile, hydrogen cyanide and acetonitrile. A process and a novel catalyst for producing acrylonitrile, acetonitrile and hydrogen cyanide, wherein the relative yields of acrylonitrile, acetonitrile and hydrogen cyanide produced using the catalyst in this process are expressed by the formula: α = [ (% AN + (3 ×% HCN) + (1.5 ×% ACN)) ÷% PC] × 100,% AN is acrylonitrile yield ≧ 81,% HCN is hydrogen cyanide yield, and% ACN is Acetonitrile yield,% PC is propylene conversion, α is greater than 100.
