PALLADIUM-CONTAINING CATALYST, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING alpha;,beta;-UNSATURATED CARBOXYLIC ACID

摘要

Disclosed is a palladium-containing catalyst which enables to highly selectively produce an E,F-unsaturated carboxylic acid from an olefin or an E,F-unsaturated aldehyde. Also disclosed are a method for producing such a catalyst and a method for producing an E,F-unsaturated carboxylic acid wherein such a catalyst is used. Specifically disclosed is a palladium-containing catalyst containing 0.001-0.25 mole of antimony element per 1 mole of palladium element or a palladium-containing catalyst containing palladium element, tellurium element and bismuth element which constitute the metal component.
