Title:
CATALYST FOR PRODUCING &agr , β-UNSATURATED CARBOXYLIC ACID AND METHOD FOR PREPARATION THEREOF, AND METHOD FOR PRODUCING &agr , β-UNSATURATED CARBOXYLIC ACID
Document Type and Number:
WIPO Patent Application WO/2005/075072
Kind Code:
A1
Abstract:
A catalyst for producing an &agr , β-unsaturated carboxylic acid which comprises a carrier having a total pore volume of 0.40 to 1.50 cc/g as measured by the nitrogen gas adsorption method and a metal carried thereon or which comprises a carrier and, carried thereon, palladium having an average particle diameter in the range of 1 to 8 nm; a method for preparing the catalyst; and a method for producing an &agr , β-unsaturated carboxylic acid using the above catalyst. The above catalyst can be suitably used for producing an &agr , β-unsaturated carboxylic acid from an olefin or an &agr , β-unsaturated aldehyde through the liquid phase oxidation in good reaction performance.
