PURPOSE: To obtain a cycloolefin in high selectivity by using a specific catalyst in a partial hydrogenation reaction of a monocyclic aromatic hydrocarbon. CONSTITUTION: In this method for producing a cycloolefin by the partial hydrogenation reaction of a monocyclic aromatic hydrocarbon in the presence of a catalyst and water, a reduced substance comprising (1) rethenium and (2) a promotor containing at least one selected from the group consisting of manganese, cobalt, nickel, zinc, chromium and lanthanide is formed so as to previously reduce the weight ratio of the promotor component to ruthenium in the reduced substance and used as a catalyst. |
