PURPOSE:To produce methyl isobutyl ketone useful as an organic solvent by one stage, by using a catalyst comprising palladium and niobium pentoxide heat-treated in a specific temperature range as essential components of catalyst and reacting acetone with hydrogen. CONSTITUTION:Acetone is reacted with hydrogen by the use of a novel highly active catalyst consisting of palladium and niobium pentoxide which is heat- treated at 400-550 deg.C and dehydrated to give methyl isobutyl ketone. In the catalyst, palladium may be supported on the niobium pentoxide and the amount of palladium used is 0.001-10%, preferably about 0.01-5% based on niobium pentoxide by weight ratio. EFFECT:The reaction can be advantageously advanced by using the catalyst having high activity, high selectively, high stability and high power. |
