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: Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing molybdenum, phosphorus, arsenic, copper and oxygen have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, methacrolein is oxidized to methacrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable byproducts.
