Method for producing catalyst for producing methacrylic acid, catalyst produced by this method, and method for producing methacrylic acid |
| abstract |
PROBLEM TO BE SOLVED: To provide a long-life catalyst used for producing methacrylic acid by gas phase catalytic oxidation of methacrolein with molecular oxygen, a method for producing the same, and methacrylic acid using this catalyst And a method for producing the same. SOLUTION: The catalyst for producing methacrylic acid of the present invention comprises Z A solution or slurry containing an element (at least one element selected from the group consisting of potassium, rubidium and cesium) and a solution or slurry containing at least molybdenum, phosphorus and vanadium and containing no Z element are mixed. A solution or slurry containing ammonium and not containing Z element is mixed in the mixed solution, and a solution or slurry containing Z element is further mixed to prepare a solution or slurry containing a catalyst precursor, which is dried and calcined. Manufactured. |
