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.

Abstract: Metharylic acid (I) was prepd. from methacrolein(II) by oxidn. with mo1. 0 at 200-600≦̸C in the presence of a catalyst contg. an oxide of W,P,U,Mo, and Co, Rn, Cd, Sr. An aq. slurry of MoO3 86.2, 85 % H3Po4 7.7, V2O3 7.5, and NH4 paratungstate 10.8 was refluxed overnight, evapd., and dried overnight at 120≦̸C to prepare a catalyst giving 65.9 % conversion and 45.4 % selectivity in the oxidn. of II to I at 355≦̸C and contact time 4.8s.
