| titleOfInvention | Method for producing catalysts for producing α,β-unsaturated carboxylic acids, and methods for producing α,β-unsaturated carboxylic acids and α,β-unsaturated carboxylic acid esters |
| abstract | A catalyst for producing α,β-unsaturated carboxylic acid having a high yield of α,β-unsaturated carboxylic acid is provided. A method for producing a catalyst for producing an α,β-unsaturated carboxylic acid, which is used when α,β-unsaturated carboxylic acid is produced by vapor phase catalytic oxidation of α,β-unsaturated aldehyde with molecular oxygen, comprising (i) at least molybdenum and A step of obtaining an aqueous slurry containing a phosphorus-containing heteropoly acid salt, (ii) a step of holding the aqueous slurry under stirring at a temperature of less than 50° C. for 2.5 to 24.5 hours, and (iii) holding the agitation obtained by the step (ii) A method for producing a catalyst for producing an α,β-unsaturated carboxylic acid, characterized by comprising a step of spray drying the aqueous slurry. |
