Title:
CATALYST FOR SYNTHESIZING METHACROLEIN AND METHACRYLIC ACID, AND METHOD FOR MANUFACTURING METHACROLEIN AND METHACRYLIC ACID
Document Type and Number:
Japanese Patent JP3790080
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst for synthesizing methacrolein and methacrylic acid, which shows superb catalytic activity and outstanding selection characteristics for methacrolein and methacrylic acid and a method for manufacturing the methacrolein and the methacrylic acid using the catalyst.
SOLUTION: This catalyst for synthesizing the methacrolein and the methacrylic acid is manufactured by drying a mixed solution or aqueous slurry containing at least molybdenum and bismuth and crushing a primary molding obtained by primarily molding a powdery baked product undergoing the baking process of the obtained dried product and further, secondarily molding the crushed pieces of the obtained primary molding. In addition, the method for manufacturing the methacrolein and the methacrylic acid is characterized in that it uses the catalyst.
