A multimetal oxide composition which comprises, as basic constituents, the elements Mo, V, W, Cu and Ni in oxidic form, with the proviso that the following molar ratios exist between the various elemental constituents: Mo:V=12:1 to 2:1, Mo:W=60:1 to 3:1, Mo:Cu=24:1 to 2:1, and Cu:Ni=5:1 to 1:3, wh
A multimetal oxide composition which comprises, as basic constituents, the elements Mo, V, W, Cu and Ni in oxidic form, with the proviso that the following molar ratios exist between the various elemental constituents: Mo:V=12:1 to 2:1, Mo:W=60:1 to 3:1, Mo:Cu=24:1 to 2:1, and Cu:Ni=5:1 to 1:3, which conforms to the empirical formula I Mo12VaWbCucNidX1eX2fX3gX4hX5iOn where X1 is one or more alkali metals, X2 is one or more alkaline earth metals, X3 is chromium, manganese, cerium and/or niobium, X4 is antimony and/or bismuth, X5 is silicon, aluminum, titanium and/or zirconium, a is from 1 to 6, b is from 0.2 to 4, c is from 0.5 to 6, d is from 0.2 to 6, c:d is from 5:1 to 1:3, e is from 0 to 2, f is from 0 to 3, g is from 0 to 5, h is from 0 to 40, i is from 0 to 40 and n is a number which is determined by the valency and occurrence of the elements in formula I other than oxygen. A process for the preparation of a multimetal oxide composition which comprises, as basic constituents, the elements Mo, V, W, Cu and Ni in oxidic form, with the proviso that the following molar ratios exist between the various elemental constituents: Mo:V=12:1 to 2:1, Mo:W=60:1 to 3:1, Mo:Cu=24:1 to 2:1, and Cu:Ni=5:1 to 1:3, which comprises producing an intimate dry mix of starting compounds which contain the elemental multimetal oxide constituents, and calcining said dry mix at from 100°to 500°C.
