<p>A method is provided for the production of 1-(4 min -isobutylphenyl)ethanol (IBPE) comprising hydrogenating 4-isobutylacetophenone (IBAP) in the absence of a solvent using as a catalyst a treated activated sponge nickel catalyst, e.g., Raney nickel, obtained by subjecting such a catalyst wetted with a protective liquid composed preponderantly of water to a washing treatment with an organic washing liquid in which the aqueous protective liquid is substantially soluble and which is substantially soluble in IBAP or IBPE, e.g., a lower alkanol such as methanol, ethanol or isopropanol. The catalyst optionally may also be washed with IBAP or IBPE after the wash with the organic washing liquid and before being used in the hydrogenation reaction. The washing treatment results in substantially higher conversions IBAP and increased yields of IBPE with a practical reaction time.</p> |
