Chemical Properties and Dissolution of Hydrazine Hydrate
Hydrazine hydrate is strongly alkaline. Contact with metal oxides and porous oxides such as mercury and copper that are easy to be reduced will cause fire and decomposition. It can erode glass, rubber, leather, cork, etc. Dehydrate. Decomposition into N2, NHa and H2 at high temperature; Hydrated callus has strong reducibility, and it is associated with halogen, HNO3, KMnO; It can absorb CO2 in the air and produce smoke. In contact with oxidant, it will ignite spontaneously.
