Abstract The synthesis of piperazine and its derivatives from hydroxylamine was discussed in this paper.From N-(2-hydroxy-ethyl)-ethylenediamine,piperazine was prepared in a cyclization reaction in a yield above 95%.A catalyst containing nickel,copper,chrome,zinc and manganese using ��-Al_2O_3 as carrier was selected.The optimum conditions were determined.2-methylpiperazine and cis-2,6-dimethylpiperazine were prepared according to the similar routes.
