Abstract This paper is concerned about the catalyst for the synthesis of piperazine with N (�� hydroxyl ethyl) ethylenediamine (HEDA) as raw material.A new supported copper catalyst with high reactivity and selectivity was developed.In the presence of Cu Cr Mn/�� Al 2O 3 catalyst and under hydrogen pressure at 180��,the reaction proceeded effectively to give piperazine in 2 hours with a yield as high as 88%,while the conversion was over 98%.
