Beschreibung
Zusammenfassung:	A mixed metal oxide catalytic system consisting of molybdenum, vanadium, palladium, lanthanum, niobium and X, wherein X is copper and/or chromium, providing higher yields of acrylic acid and acrolein in the low temperature oxidation of propylene with a molecular oxygen-containing gas without the production of side products such as CO. Système catalytique à base d'oxydes métalliques constitué par molybdène, vanadium, palladium, niobium et X, X consistant en cuivre et/ou chorme, et permettant d'obtenir des quantités supérieures d'acide acrylique et d'acroléine dans l'oxydation à basse température de propylène avec un gaz contenant oxygàne moléculaire sans génération de produits secondaires, tels que CO.
