<p>PURPOSE:To improve the yield easily without corrosion of apparatuses in partially hydrogenating an aromatic hydrocarbon in the presence of a supported rutheniumcatalyst and water to give the titled compound which is an intermediate raw material for medicines, etc., by using specific compounds as a catalyst carrier and additive. CONSTITUTION:An aromatic hydrocarbon is partially hydrogenated in the presence of a supported catalyst containing barium sulfate as a carrier and ruthenium supported thereon as a catalyst and at least one or more metal sulfates selected from the group consisting of lithium, cobalt, iron and zinc as an additive added thereto at 0-250 deg.C, preferably 100-200 deg.C to give the corresponding cycloolefin. The ratio of the supported ruthenium in the above-mentioned catalyst is 0.01-20wt%, preferably 0.1-10wt%. The concentration of the metal sulfate which is an additive used is preferably within 1:5-1:250 atomic ratio range of the metal species to the ruthenium in the catalyst to be used for the reaction.</p> |
