Product Name: Hydrazine Hydrate
Hydrazine hydrate, also known as hydrazine hydrate. The pure product is colorless and transparent oily liquid, with light ammonia smell, smoking in wet air, strong alkalinity and hygroscopicity. Under normal pressure, hydrazine can form azeotrope with water (the content of hydrazine in azeotrope is about 69%). Hydrazine hydrate solution or hydrazine salt with 40% – 80% content is generally used in industry, and the content can reach 100%. Hydrazine hydrate liquid exists in the form of dimer, and is miscible with water and ethanol, but insoluble in ether and chloroform; it can corrode glass, rubber, leather, cork, etc., and decomposes into N2, NH3 and H2 at high temperature; hydrazine hydrate has strong reducibility, and reacts with halogen, HNO3, KMnO4, etc., which can absorb CO2 in the air and produce smoke. Hydrazine hydrate and its derivatives are widely used in many industrial applications, such as reducing agent, antioxidant, pharmaceutical and foaming agent.

A. It is used to synthesize foaming agent
Using hydrazine hydrate as raw material, the gas generation of ADC foaming agent is much higher than that of other similar products, and the product is non-toxic, tasteless, colorless and non deteriorating.
B. For the synthesis of pesticides:
More than 100 kinds of pesticides were synthesized from hydrazine hydrate and triazole derivatives of hydrazine.
C. Pharmaceutical industry:
There are many kinds of medicines synthesized from hydrazine hydrate and its derivatives, such as cephalosporins and rifampicin.
D. Used as deoxidizer:
Because hydrazine is reductive, it reacts with oxygen to form nitrogen and water. It has the characteristics of non-toxic, non corrosive and rapid oxygen removal. Therefore, hydrazine is often used as water medium deoxidizer, and the largest dosage is boiler feed water deoxidization.
E. It can be refined to make rocket fuel.
F. It can be used to refine precious metals.
G. Passenger car airbags, etc.
