PRODUCTION METHOD FOR CATALYST FOR METHACRYLIC ACID PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a production method for a catalyst for methacrylic acid production by which moldings are produced at high productivity while fluctuations in property and performance of the moldings are suppressed to little. SOLUTION: The production method for the catalyst for methacrylic acid production is used for producing methacrylic acid by subjecting methacrolein to gaseous phase contact oxidation by using molecular oxygen, wherein catalyst composition powder containing at least molybdenum and phosphorus is made into tablets of two pieces or more simultaneously at one shot compression operation.
