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 Mo12 P0.1-3 M0.1-3 CU0.01-2 V0.01-2 X0.01-2 M' a 0b (I) where M is at least one of K, Rb and Cs; X is at least one of Ba, La, Ca, Al, Ag, Cd, Ti, Tl, HB, 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
