N-乙基哌嗪合成方法的改进
Improvement on the Synthesis of N-ethylpiperazine
【摘要】 以哌嗪水溶液与溴乙烷反应合成N乙基哌嗪,并以共沸蒸馏方法分离N乙基哌嗪及副产物N,N′二乙基哌嗪。合成方法具有新颖、简便、收率及纯度高的特点,适合于工业生产。
【Abstract】 N ethylpiperazine was prepared by the reaction of piperazine and ethylbromide. The separation of N ethylpiperazine and N,N′ diethylpiperazine was through azeotropic distillation which is very simple.
