ABSTRACT:
A catalytic system based on oxygen, vanadium, phosphorus, and molybdenum corresponding to the formula H.sub.m X.sub.n Me.sub.p PMo.sub.12-x V.sub.x O.sub.40, wherein X represents the VO.sup.2+ cation with 0<n.ltoreq.2, H represents protons with 0.ltoreq.m<4, 0.ltoreq.x.ltoreq.3, Me is a metal ion, especially an ion of a transition metal, with 0.ltoreq.p.ltoreq.t, t depending on the charge of the corresponding ion, is useful for the oxydehydrogenation of saturated carboxylic acids to .alpha.,.beta.-unsaturated acids and for oxidizing aldehydes to acids.
