Hydrazine hydrate is a colorless, transparent, oily liquid with a light ammonia smell. In industry, hydrazine hydrate aqueous solution or hydrazine salt with a content of 40% to 80% is generally used. Relative density 1.03 (21℃); melting point -40℃; boiling point 118.5℃. Surface tension (25℃) 74.OmN/m, refractive index 1.4284, heat of formation -242.7lkj/mol, flash point (open cup) 72.8℃. Hydrazine hydrate is strongly alkaline and hygroscopic. Liquid hydrazine hydrate exists in the form of dimer, miscible with water and ethanol, insoluble in ether and chloroform; it can corrode glass, rubber, leather, cork, etc., and decompose into Nz, NH3 and Hz at high temperature; hydrazine hydrate has extremely strong reducing properties, and reacts violently with halogens, HN03, KMn04, etc. It can absorb C02 in the air and produce smoke.

Important use of hydrazine hydrate

Hydrazine Hydrate is a liquid hydrazine oxygen scavenger. Hydrazine Hydrate reacts with dissolved oxygen and forms a protective film in the boiler system, It will react with O2 in the water to form H2O and N2. Product use yields an alkaline environment and therefore, not only oxygen but also carbonic acid levels are controlled.

Direct application of hydrazine hydrate

1. Anticorrosion additive used for circulating water in thermal power plants and nuclear power plants. 2. Deoxidizer for water used in industrial boilers and high-pressure steam boilers. Hydrazine hydrate is a deoxidizer, which can reduce the dissolved oxygen in water and is used to further remove the residual trace dissolved oxygen in boiler feed water after thermal deoxidization. Because dissolved oxygen in feedwater will cause corrosion of boiler tube wall. Adding hydrazine hydrate to the boiler feed water can not only deoxidize, but also prevent the formation of iron scale and copper scale in the boiler.
