Abstract
Compositions of the empirical formula: Mo.sub.12 P.sub.0.1-3 M.sub.0.1-3 Cu.sub.0.1-2 V.sub.0.1-2 X.sub.0.01-2 Y.sub.a O.sub.b (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; Y 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, are excellent catalysts for the oxidation of methacrolein to methacrylic acid.
