Abstract: A novel method for industrially advantageously hydrogenating a phenol. The method of phenol hydrogenation comprises subjecting a phenol to a hydrogenation reaction in the presence of carbon dioxide which participates in the reaction, and is characterized by using a supported rhodium and/or ruthenium catalyst to thereby efficiently hydrogenate the phenol at a lower temperature than in conventional methods. The method may be characterized in that carbon dioxide having a temperature of 20 to 250°C and a pressure of 0.1 to 50 MPa is used as the carbon dioxide. The method may be further characterized by using hydrogen under the conditions of a temperature of 20 to 250°C and a pressure of 0.1 to 50 MPa. A phenol hydrogenation process which uses no harmful organic solvents and is environmentally less harmful can be realized.
