Abstract: The main synthetic route and domestic manufacture of piperazine and its major N-substituted derivatives were reviewed in this paper. Piperazine can be synthesized by using N-β-hydroxyethyl ethylenediamine, diethylenetriamine, ethylenediamine, ethanolamine and other raw materials. Among them, the route using N-hydroxyethyl ethylenediamine as the starting material is believed as the most efficient route for the synthesis of piperazine. N-substituted derivatives of piperazine can be synthesized via either piperazine and N-alkyl agents or related primary amines, ethylene oxide and ammonia. Synthesis and manufacture of piperazine and its N-substituted derivatives have broad prospects of development due to their wide application areas and huge demand.

Key words: piperazine, derivatives, N-β-hydroxyethyl ethylenediamine
