In a high pressure glass bomb (ca. 20 ml), 200 mg. of the catalyst prepared above, 2 ml. of benzene, and 5 ml. of 40% sulfuric acid were provided with a small bar magnet coated with polytetrafluoroethylene. After replacement with hydrogen, the bomb was heated at 100° C. under 10 Kg/cm2G pressure of hydrogen for 4 hours with magnetic stirring. After neutralization with about 13 ml. of aqueous alkali (ca. 40%K3PO4 -NaOH), the product was submitted to gas-liquid chromatography (column: 25%PEG-4000/C-22, 60-80 mesh, 3 m., 150° C., H2 20 ml./min). The chromatogram showed that the conversion of benzene was 1.39%, and the yields of cyclohexanol, cyclohexane, and cyclohexene were 0.42%, 0.77%, and 0.20%, respectively. The selectivity of cyclohexanol was 30%.
