Anhydrous piperazine is a colorless crystal. It is an important pharmaceutical intermediate and fine chemical raw material used in high-performance polymers, with a wide range of applications. In recent years, extensive and in-depth research has been conducted on its synthesis process both domestically and internationally. Currently, the main raw materials for synthesizing anhydrous piperazine domestically and internationally include ethanolamine, N-hydroxyethyl ethylenediamine, and polyethylenepolyamine. Anhydrous piperazine must be stored in a dry, ventilated, and light-protected area.

Anhydrous piperazine is an important fine chemical raw material with extremely broad applications. Although anhydrous piperazine has been developed, it has not yet reached full production capacity, and the process requires further refinement. Due to its wide range of uses, the market price of anhydrous piperazine is typically about 2.5 times that of piperazine hexahydrate. Currently, China's production of piperazine, especially anhydrous piperazine, is too low to meet market demand. Of the annual import volume of 2,000–2,500 tons, 90% is anhydrous piperazine. In addition to its use in pharmaceutical intermediates, the applications of piperazine in other fields are continuously expanding. Anhydrous piperazine (PIP)
