Procedure

41.2 mL of the coated catalysts obtained in Examples 1, 3 and 4 were filled in a stainless reaction tube with an internal diameter of 18.4 mm. A raw material gas (composition (molar ratio); methacrolein:oxygen:water vapor:nitrogen=1:2:4:18.6) was flowed into the reaction tube at 300 hr−1 of space velocity (SV), and methacrolein conversion rate, methacrylic acid selectivity and methacrylic acid yield were determined 24 hours after beginning of the reaction.
