Synthesis of N-Ethylpiperazine

N Ethylpiperazine was synthesized from piperazine and bromoethane through alkylation reaction.Effects of the ratio of reactants,reaction time,reaction temperature,kind of catalyst and other conditions on the yield of the product were studied.The optimal reaction conditions were obtained,under which the yield of N ethylpiperazine was above 90%.Purity of N ethylpiperazine reached 99%.
