Abstract: PURPOSE: A cyclic hydrogenation method of aromatic diamine is provided for reducing reaction time and decreasing amount of by-product to raise yield of product by preliminarily surface treating ruthenium catalyst with oxygen or air without using basic materials. CONSTITUTION: The method for producing cyclo-aromatic diamine is to cyclically hydrogenate aromatic diamine at 50-250 deg.C and 300-4000 psig of pressure under 0.1-5 wt.% ruthenium catalyst surface-treated with air or oxygen at 50-200 deg.C. and in the presence of organic solvent. The ruthenium catalyst is prepared by immersing the catalyst into a carrier selected from a group consisting of activated carbon, calcium carbonate, ceria, alumina, zirconia, titania and silica in an amount of 1-10 wt.%. The organic solvent is any one selected from a group consisting of diethylether, isopropylether, methanol, ethanol, isopropylalcohol, butanol, tetrahydrofuran and dioxane.
