The cyclization of β-hydroxyethylenediamine in the presence ofcatalytic hydrogenation was investigated in the present paper.Several Cu-Containing catalysts were prepared and examined for this cyclization.Toluene was employed as solvent to increase the reaction selectivity.The other parameters were optimized.Thus,in the presence of Cu/γ-Al2O3 and Hydrogen(3.0MPa),β-hydroxyethylenediamine in toluene,180℃～190℃,was found to undergo effective cyclization to afford piperazine in 85% yield.
