<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst for methacrylic acid production, this catalyst which can manufacture methacrylic acid at a high yield by subjecting methacrolein to a gas phase catalytic oxidization with a molecular oxygen and also, which includes molybdenum and phosphorus as catalytic components. <P>SOLUTION: This method for manufacturing a catalyst for methacrylic acid production comprises a process to knead particles including a catalytic component, an organic binder and a liquid, and a process for extrusion-molding the obtained kneaded product. The addition rate of the liquid in the kneading process, is 0.4 to 1 pt.mass/min per 1 pt.mass of the particles including the catalytic component. <P>COPYRIGHT: (C)2011,JPO&INPIT |
