PROBLEM TO BE SOLVED: To provide an unsaturated carboxylic acid production process by using a catalyst having both a high catalyst capability and a strong mechanical strength.SOLUTION: Provided is an unsaturated carboxylic acid production process in which a supported catalyst obtained by feeding a catalytically active component containing a liquid binder component and molybdenum and vanadium, and/or a precursor thereof, into a rolling granulator and granulating at a relative centrifugal acceleration of 0.5 G or more and 30 G or less, is used. |
