Abstract
A catalyst composition useful for the oxidation of olefins, particularly the oxidation of propylene and isobutylene to produce the corresponding unsaturated aldehydes acrolein and methacrolein, respectively, comprises the combination of oxides of molybdenum, cobalt, iron, bismuth, thallium and antimony, and preferably also silicon. When the catalyst is used for the vapor-phase oxidation of the olefins with molecular oxygen, the aldehydes are produced with high selectivity. Alcohol precursors for the olefins can be used as feed instead of the olefins themselves.
