METHOD FOR PRODUCING PALLADIUM-CONTAINING CATALYST

摘要

Disclosed is a palladium-containing catalyst for producing an a,ß-unsaturated carboxylic acid from an olefin or an a,ß-unsaturated aldehyde with high productivity. Also disclosed are a method for producing such a catalyst, and a method for producing an a,ß-unsaturated carboxylic acid with high productivity. Specifically, a palladium-containing catalyst is produced by a method which has a step wherein palladium in the oxidation state is reduced by a compound (A) represented by the following formula (1).
