Allgemeine Beschreibung

Piperazine (PZ) is an amine solvent. The ability of aqueous PZ to absorb carbon dioxide (CO2) has been assessed. It is reported to cause paralysis in Ascaris worms. The analysis of the crystal structure of PZ at 150K shows the presence of layered structure with NH...N hydrogen-bonded chains.

Anwendung

Intermediate for a wide range of pharmaceuticals, polymers, dyes, corrosion inhibitors, rubber accelerators and surfactants.
Piperazine may be used in the preparation of N-(hetero)arylpiperazines.
