The reaction temperature is generally 20-250 deg.C, preferably 50-180 deg.C and the pressure is normal or elevated. The ion-exchange type laminar clay is prepared by exchanging at least a part of alkali metal ions such as sodium ions in the laminar clay with other metal ions. The laminar clay is preferably a fluorine-containing synthetic mica. On the reaction, the amount of the catalyst is 0.001-3pts.wt., preferably 0.01-0.5pt.wt. per 1pt.wt. of the alcohol.

Abstract: PROBLEM TO BE SOLVED: To obtain 4-hydroxycyclohexanone useful as a raw material for various medicines, industrial chemicals, etc., by carrying out hydrogenation of hydroquinone in the presence of a specific catalyst. SOLUTION: Hydroquinone is hydrogenated by using a palladium activated carbon supporting catalyst obtained by supporting a palladium catalyst on activated carbon in a hydrocarbon solvent (e. g. mesitylene) in the presence of a compound having an acid catalytic action at 50-300 deg.C under 1-20 atmospheric pressure to give 4-hydroxycyclohexanone. The activated carbon used as the catalyst is the one obtained by steam activation treatment of wood and has 1,100-1,300m /g specific surface area. Preferably, the catalyst is reduced in hydrogenation activity by sulfur poisoning. A synthetic mica having a solid acid point is preferably used as the compound having an acid catalytic action. The objective substance is obtained under safe and mild conditions and is readily separated and extracted from the reaction solution after the completion of the reaction.
