Beschreibung
Zusammenfassung:	FIELD: industrial organic synthesis. ^ SUBSTANCE: invention provides catalyst for production of methyl ethyl ketone via oxidation of n-butenes by oxygen and/or oxygen-containing gas, which catalyst is composed of aqueous solution of molybdeno-vanado-phosphoric heteropolyacid or mixture of the latter with its salt and 5.10-4 to 1.10-2 M palladium stabilized by phthalocyanine ligand at palladium-to-phthalocyanine molar ratio 0.5-2. Mo-V-phosphoric heteropolyacid is depicted by formula H19P3Mo18V7O84. concentration of vanadium being 0.4 to 2.2 g-atom/L. Oxidation of n-butenes is carried out continuously in two steps at temperature 15 to 90. Catalyst is regenerated in contact with oxygen or oxygen-containing gas at 140-190 and oxygen pressure 1-10 gauge atm. ^ EFFECT: enhanced process efficiency due to increased stability of catalyst components. ^ 7 cl, 1 dwg, 6 tbl, 7 ex
