Abstract: Methacrylic acid was prepd. by the oxidn of methacrolein by air at 288-371≦̸C over mixed oxide catalysts A0.05 Rb0.5 Mo3 P0.33 Ox (A= one or more of As, K, Ca, Cd, V, U, Ce, W, Ni, Zr, Ba, Fe, In, Tl, Rh, Sn, Mn, Re, Ru, Co or Cu; x=a no. detd. by the valence and nox. of other atoms present). Total conversion, signale pass yields and selectivities were 47.7-100, 13.6-69.5 and 28.5-82.1% resp.. Thus, with In0.05 Rb1.5 Mo3 P0.33 On at 243≦̸C, total conversion of aldehyde was 85.5%, with a signal pass yield of 62.0% and selectivity to methacrylic acid of 71.3%

Abstract: Catalysts containing the oxides of molybdenum and phosphorus promoted with rubidium and at least one element selected from the group consisting of As, Cd, In, Sn, Tl, K, Ca, V, U, Ce, W, Ni, Zr, Ba, Fe, Rh, Mn, Re, Ru, Co, and Cu have been found to be especially desirable in the vapor phase oxidation of acrolein and methacrolein with molecular oxygen to yield acrylic acid and methacrylic acid respectively. The reaction of methacrolein gives an especially pure product in high yields and selectivities of methacrylic acid.
