    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.

    Abstract: Olefinic acids and esters, such as methacrylic acid and methylmethacrylate, are prepared by contacting in the presence of molecular oxygen the corresponding saturated acid or ester, such as isobutyric acid or methylisobutyrate with the catalyst of the empirical formula: Mo12P0.1-3M0.1-3Cu0.01-2V0.01-2X0.01-2M'aOb (I) where M is at least one of K, Rb and Cs; X is at least one of Ba, La, Ga, Al, Ag, Cd, Ti, Tl, Hg, Pb and Zn; M' is at least one of Fe, Co, Ni, Sr, Mn, In, Ta, Ge, S and Be when a >0; a is a number of 0 to about 2; and b is a number that satisfies the valence requirements of the other elements present.
