Abstract: In this paper, it is reported that iso-butyralaldehyde (IBA) is directly oxided to methacrylic acid (MAA) by P, Mo, Vheteroacid salt containing rare earth. In space velocity 1500 hr-1 and IBA: O2:H2O:N2 = 1:2.5,: 7:10 (mole ratio) conditions, yield of MAAis 63% and yield of methacrolein is 15% in single way, total yield of MAAexceeds 70%. Comparing with two step method of iso-butyralaldehyde oxidation, yield of MAAis raised over 10% and difficulty of separating iso-butyric acid and MAAcan be avoided. The method is the most economical route.
