摘要：
This invention relates to a method for preparing cycloaliphatic diamines by hydrogenating an aromatic diamines in the presence of a supported ruthenium catalyst. The catalyst is pre-treated with oxygen or air to increase the rate of the reaction and decrease the amount of higher boiler by-products.
