Abstract: A process for obtaining acrylic acid or methacrylic acid from acrolein or methacrolein, respectively, comprising the steps of mixing the aldehyde, molecular oxygen and water vapor in a molar ratio within the range of 1/0.5-5/0-20, respectively; contacting said mixture with a catalyst at a temperature of about 200º to 500º c, said catalyst having a composition represented by the empirical formula ** (formula) ** wherein x is a metal selected from the group consisting of antimony and germanium, or both, and where a is a number from 6 to about 18, b, c and d are, individually, from about 0.1 to about 6, and e is the number of oxygen atoms required to meet the valence requirements of the other metals present; and recover the unsaturated acid.
