More Information
Summary:Disclosed is a method for producing a catalyst for producing methacrylic acid by subjecting methacrolein or the like to vapor phase catalytic oxidation, which contains, as essential active components, Mo, V, P, Cs, NH 4 and Cu, the method including (a) a step of preparing a heteropoly acid aqueous solution or the like (A liquid) containing, as constituent elements, Mo, P and V; (b) a step of mixing a part of the resulting A liquid with a cesium compound aqueous solution or the like (B liquid); and (c) a step of mixing the remainder of the A liquid with the B liquid to prepare a slurry liquid (C liquid).
