    Abstract: Olefinic aldehydes were oxidized to olefinic acids such as methacrolein, acrolein to methacrylic acid acrylic acid, at 200-500≦̸C over mixed oxide catalysts contg. Mo, P, As and Cu. Thus, a 1:5.7:4.6:8.6 (molar) mixt. of methacrolein, air, N, and steam was passed at a 2-sec-residence time through a tube heated at 354≦̸C and contg. the mixed oxide catalyst on an Alundum support to give methacrylic acid in 93.8% yield.
