Beschreibung
Zusammenfassung:	Provided are a catalyst which, in a reaction. for producing a conjugated diolefin by catalytic oxidative dehydrogenation from a mixed gas including a monoolefin having 4 or more carbon atoms and molecular oxygen, may suppress the production of a coke-like substance and improve the long-term stability of the reaction; and a method for producing the same. Disclosed is a composite metal oxide catalyst for producing a conjugated diolefin by a gas phase catalytic oxidative dehydrogenation reaction from a mixed gas including a monoolefin having 4 or more carbon atoms and molecular oxygen, the composite metal oxide catalyst having a solid acidity of 35 to 172 μmol/g.
