    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.

    Abstract: Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing molybdenum, phosphorus, arsenic, copper and oxygen have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, methacrolein is oxidized to methacrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable byproducts.
