CATALYST FOR PRODUCTION OF α,β-UNSATURATED CARBOXYLIC ACID

PROBLEM TO BE SOLVED: To provide a catalyst for production of an α,β-unsaturated carboxylic acid from an olefin or an α,β-unsaturated aldehyde in a high yield, a method of manufacturing the catalyst and a method of producing an α,β-unsaturated carboxylic acid in a high yield. SOLUTION: The catalyst consists of an activated charcoal of a specific surface area of 100-1,000 m 2 /g supporting a noble metal. The method of manufacturing the catalyst comprises selecting an activated charcoal of a specific surface area of 100-1,000 m 2 /g and making a noble metal supported by the charcoal. The method of producing the carboxylic acid comprises oxidizing an olefin or an α,β-unsaturated aldehyde with molecular oxygen in a liquid phase in the presence of the catalyst. COPYRIGHT: (C)2004,JPO
