摘要：
A catalytic oxide, particularly adapted for the preparation of unsaturated carbonyl compounds through the catalytic vapor phase oxidation of olefins, wherein the atomic ratio among the constituent elements, Co:Fe:Bi:W:Mo:Si:Z, is within the range of 2.0-20.0 : 0.1-10.0 : 0.1-10.0 : 0.5-10.0 : 2.0-11.5 : 0-15.0 : 0.005-1.0, with the proviso that W plus Mo equals 12.0, and Z represents an alkaline earth metal.
