White Crystal, easy to absorb moisture. Melting point 44. Boiling point 125~130 deg C. Soluble in water and ethanol, insoluble in ether, its aqueous solution was weak alkaline reaction. With the distillation of zinc, namely the formation of piperazine. Flash point 87.
piperazine hexahydrate was prepared from chloroethanol by ammoniation and ring synthesis of piperazine hydrochloride followed by neutralization with sodium hydroxide.
This product is mainly used for the production of intestinal insect drug piperazine phosphate, piperazine citrate, and fluphenazine, strong pain, rifampicin. Piperazine hexahydrate is dissolved in ethanol, and acetic acid is added to stir and cool to precipitate piperazine acetate, which can be used to synthesize hormone drug prednisolone sodium phosphate. Piperazine hexahydrate can also be used in the production of acetylpiperazine pharmaceutical intermediates. Piperazine is also used in the production of wetting agents, emulsifiers, dispersants and other surfactant products, the production of antioxidants, preservatives, stabilizers, plastic processing aids and rubber additives.
Introduction | piperazine (hexahydrate) belongs to heterocyclic organic compounds, which can be used in the synthesis of pharmaceuticals and organic compounds. |
Application | used in the synthesis of pharmaceuticals and organic compounds used in the synthesis of nifuroperazone (Nifurpipone), rifampicin and acetylpiperazine and other drugs. used in the pharmaceutical, shipbuilding and plastics industries. |
production method | piperazine hexahydrate was prepared by ammoniation and ring synthesis of piperazine hydrochloride from chloroethanol, followed by neutralization with sodium hydroxide, the reaction formula is as follows: |
