Title:
CATALYST FOR &agr ,ß-UNSATURATED CARBOXYLIC ACID PRODUCTION, PROCESS FOR PRODUCING THE SAME, AND PROCESS FOR PRODUCING &agr ,ß-UNSATURATED CARBOXYLIC ACID
Document Type and Number:
WIPO Patent Application WO/2004/037411
Kind Code:
A1
Abstract:
A catalyst for &agr ,ß-unsaturated carboxylic acid production which comprises activated carbon having a specific surface area of 100 to 1,300 m2/g and a noble metal deposited thereon. The catalyst enables an &agr ,ß-unsaturated carboxylic acid to be produced in high yield from an olefin or &agr ,ß-unsaturated aldehyde. This catalyst can be produced by a process for producing a catalyst for &agr ,ß-unsaturated carboxylic acid production, the process comprising selecting an activated carbon having a specific surface area of 100 to 1,300 m2/g and depositing the noble metal on the activated carbon.
