PURPOSE:To obtain the titled compound useful as an organic solvent in one step at a low cost, by reacting acetone with hydrogen in the presence of a catalyst having high activity and selectivity and composed of Pd and an oxide or hydroxide of at least one kind of metal selected from Ce, Hf and Ta. CONSTITUTION:Methyl isobutyl ketone is produced by reacting acetone with hydrogen in the presence of a catalyst composed of palladium (especially Pd-C, Pd-alumina, etc.) and an oxide or hydroxide of at least one metal selected from cerium, hafnium and tantalum [e.g. Ce(OH)4, CeO2, HfO(OH)2, tantalic acid, etc.]. The amount of Pd in the catalyst is preferably about 0.01-5wt% based on said oxide or hydroxide. |
