摘要：PROBLEM TO BE SOLVED: To produce an unsaturated carboxylic acid such asacrylic acid and methacrolein from an unsaturated aldehyde such as acrolein andmethacrolein as a catalyst used in a vapor phase catalytic oxidation reaction, which has ahigh raw material conversion rate and product selectivity. At the same time, a method for
producing a catalyst having improved mechanical strength is provided. SOLUTION: Aliquid preparation step of integrating and heating a source compound of each catalystcomponent element in an aqueous system to prepare a liquid, a drying step of drying theprepared liquid to make a powder, and the powder. Including a molding step of moldingto use as a catalyst precursor and a firing step of firing the catalyst precursor to use as acatalyst, in the molding step, a fatty acid metal salt having 15 to 20 carbon atoms isadded to 100 parts by weight of the powder before molding. Is added in an amount of0.03 parts by weight or more and 0.48 parts by weight or less. [Selection diagram] Fig. 1
