ABSTRACT:
A catalyst composition useful for the oxidation of unsaturated aldehydes, particularly the oxidation of acrolein and methacrolein to produce the corresponding unsaturated acids, acrylic acid and methacrylic acid, respectively, comprises the combination of oxides of molybdenum, copper, boron, phosphorus and antimony, an alkali metal, and optionally vanadium in predetermined relative atomic ratios. When the catalyst is used for the vapor-phase oxidation of the aldehydes with molecular oxygen, the acids are produced with a combination of good conversion and high selectivity with elevated quantities of aldehyde in the feed and at super atmospheric pressures.
