| titleOfInvention | Methacrylic acid production catalyst, methacrylic acid production catalyst precursor, their production method, methacrylic acid production method, and methacrylic ester production method |
| abstract | A catalyst capable of producing methacrylic acid at a high selectivity by subjecting methacrolein to gas phase catalytic oxidation. A methacrylic acid production catalyst having a composition represented by the following formula, which is used when methacrylic acid is produced by gas phase catalytic oxidation of methacrolein with molecular oxygen.
