摘要: A process for the preparation of unsaturated carbonyl compounds which comprises carrying out the catalytic vapor phase oxidation of an olefin selected from the group consisting of propylene and isobutylene in the presence of a catalytic oxide in which the atomic ratio among the constituent catalytic elements, Co:Fe:Bi: W:Mo:Si:Tl:Z ranges 2.0-20.0 : 0.1-10.0 : 0.1-10.0 : 0.5-10.0 : 2.0-11.5 : 0.5-15.0 : 0.005-3.0 : 0-3.0, with the proviso that W plus Mo equals 12.0, and Z stands for a metal selected from the group consisting of alakali metals and alkaline earth metals.
