Beschreibung
Zusammenfassung:	The present invention relates to a catalyst composition consisting of oxide complexes of vanadium, molybdenum and copper plus an additional metal oxide selected from the group consisting of antimony and germanium or mixtures thereof. These catalysts are especially useful for producing acrylic acid from acrolein and for producing methacrylic acid from methacrolein.
