Also, it is known that epoxidized cycloalkanes and/or epoxidized cycloalkenes can be produced by epoxidizing corresponding cycloalkenes with a high yield. If the epoxidized compounds can be converted to corresponding cycloalkanones and cycloalkanols with a high efficiency, the cycloalkanones and the cycloalkanols can be expected to be obtained at a high yield. However, only a small number of reports can be found on methods of converting an epoxidized cycloalkane and/or an epoxidized cycloalkene to a mixture of cycloalkanone with cycloalkanol. For example, J. Mol. Catal., Vol. 69, pages 69 to 103 (1991) discloses a method of hydrogenating a monoepoxycyclododecadiene with hydrogen in the presence of a catalyst comprising palladium carried on a carrier consisting of γ-alumina, under a hydrogen gas pressure of 1.3 MPa at a temperature of 90° C. In this method, cyclododecanol was produced with a yield of 20% or less and no cyclododecanone was produced. When a catalyst comprising palladium carried on a carrier consisting of titania or silica was used in place of the above-mentioned palladium catalyst carried on γ-alumina, the yield of cyclododecanol was low and unsatisfactory.
