Use and function of hydrazine hydrate

Hydrazine hydrate, also known as hydrazine hydrate, is highly alkaline and hygroscopic. The pure product is a colorless and transparent oily liquid with light ammonia smell, and smokes in wet air, with strong alkalinity and hygroscopicity. Hydrazine hydrate aqueous solution or hydrazine salt with a content of 40% - 80% is generally used in industry. Hydrazine hydrate liquid exists in the form of dimer, is miscible with water and ethanol, and is insoluble in ether and chloroform; It can erode glass, rubber, leather, cork, etc., and decompose into N2, NH3 and H2 under high temperature; Hydrazine hydrate is reductive and reacts violently with halogen, HNO3, KmnO4, etc. It can absorb CO2 in the air and produce smoke. Hydrazine hydrate and its derivatives are widely used in many industrial applications, as reducing agents, antioxidants, and in the preparation of pharmaceuticals, foaming agents, etc.

Hydrazine was synthesized in 1875 and has a history of more than 100 years. Since the end of the Second World War, the Germans have used it for rocket propellant, and its industrial production history has been more than half a century. Hydrazine is usually sold in the form of monohydrate (N2H4 • H2O), which is equivalent to 64% of the mass fraction of hydrazine. Hydrazine hydrate aqueous solution or hydrazine salt with a content of 40% - 80% is generally used in industry.
