摘要: A catalyst for producing an α, β-unsaturated carboxylic acid which comprises a carrier having total pore volume of 0.40 to 1.50 cc/g as measured by the nitrogen gas adsorption method and metal carried thereon or and, thereon, palladium average particle diameter in range 1 8 nm; preparing catalyst; using above catalyst. The can be suitably used from olefin aldehyde through liquid phase oxidation good reaction performance.
