    Abstract: Alpha , Beta -unsaturated aldehydes are oxidized to Alpha , Beta -unsaturated carboxylic acids by contacting the Alpha , Beta -unsaturated aldehyde with air or oxygen and steam at 200*350*C and at atmospheric or elevated pressure in the presence of a catalyst so as to convert the aldehyde to the corresponding carboxylic acid. The catalyst comprises a mixture of oxides of the elements antimony, molybdenum, vanadium and tungsten and/or compounds of said elements and oxygen wherein the atomic ratio of the elements is as follows: 1 to 60 : 12 : 0.5 to 25 : 0.1 to 12. The catalyst is made by intimately mixing under agitation aqueous solutions or suspensions of the oxides or other compounds, for instance antimony oxide, ammonium molybdate, ammonium vanadate and ammonium tungstate, and possibly a carrier material and preferably bringing the mixture to boiling point, then separating the catalyst mass from the aqueous phase, drying it and calcining it at 225*-275*C, followed by heating in air for 15-60 minutes at 350*-475*C.
