<p><P>PROBLEM TO BE SOLVED: To provide a palladium-containing supported catalyst for highly selectively producing anα,β-unsaturated carboxylic acid from an olefin or anα,β-unsaturated aldehyde, a method of manufacturing the catalyst and a method of producing anα,β-unsaturated carboxylic acid with high selectivity. <P>SOLUTION: In the method of manufacturing the palladium-containing supported catalyst with which theα,β-unsaturated carboxylic acid is produced from the olefin or theα,β-unsaturated aldehyde, the palladium-containing supported catalyst is manufactured by a process of the reduction of palladium oxide contained in a catalyst precursor in which at least palladium oxide is supported on a carrier. Theα,β-unsaturated carboxylic acid is also produced by liquid-phase oxidation of the olefin or theα,β-unsaturated aldehyde with molecular oxygen using the palladium containing supported catalyst. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
