Zusammenfassung:	PURPOSE:To efficiently produce a solid catalyst for synthesis of methacrylic acid from methacrolein. CONSTITUTION:A mixed soln. or an aq. slurry contg. at least Mo, P and V as catalytic components is dried, lower alcohol or acetone is added to the resulting dried product and they are extrusion-molded. Catalysts for synthesis of methacrylic acid having various shapes are easily and efficiently obtd.
