Hydrazine hydrate is a colorless compound with the chemical formula H6N2O, which is used as a reducing agent in the synthesis of many reactions and as a solvent for many mineral compounds. Generally, hydrazines are a group of organic substances that are obtained by the replacement of one or more hydrogen atoms by an organic group. This compound is obtained by some microorganisms such as bacteria, yeast, and fungi. Hydrazine, like ammonia, is a chemical base but is 15 times weaker than ammonia. This compound is used in the synthesis of many chemicals, water treatment, satellite fuel, medicine making, etc. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

The Production Process of Hydrazine Hydrate:
Commercially, this compound is produced in three ways:
Ammonia is oxidized by chlorine amine and sodium hypochlorite. Chloramine then reacts with excess sodium hydroxide and ammonia to produce an aqueous solution of hydrazine or hydrazine hydrate. During this reaction, sodium chloride is produced as a by-product.
This process involves the oxidation of ammonia with hydrogen peroxide in the presence of nitrile or an amide group to form an azine that is further hydrolyzed to produce hydrazine hydrate.
In this process; hydrogen peroxide is used to oxidize ammonia in the presence of ketones.
Hydrazine Hydrate Uses:
This material is used for many industrial applications including the Preparation of polymeric foam, polymerization catalysts, pesticides, and the gas used in airbags.
