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.

Hydrazine hydrate emergency treatment methods
Evacuate personnel in the leaked contaminated area to a safe area and prohibit unrelated personnel from entering the contaminated area. It is recommended that emergency responders wear self-contained breathing apparatus and chemical protective clothing. Do not come into direct contact with the leakage, and plug the leakage when it is safe to do so. Spray water to reduce evaporation. Use a dry ice carbon dioxide fire extinguisher or mix and absorb it with sand, soil or other non-flammable adsorbents, then collect and transport it to a waste disposal site for disposal. You can also rinse with large amounts of water and put the diluted wash water into the wastewater system. If there is a large amount of leakage, use dikes to contain it, then collect, transfer, recycle or dispose of it after harmless treatment.

Why is hydrazinium hydroxide solution added to boiler feed water?
In order to prevent the boiler water system and pipelines from being corroded by oxygen, and to ensure the complete elimination of residual dissolved oxygen after thermal deaeration and oxygen leaking into the feed water due to loose pumps and water supply systems, it is necessary to add an appropriate amount of combined oxygen to the feed water. ammonia. Hydrazine (N2H4) is also called hydrazine, and its hydrate is commonly used, hydrazine hydrate (N2H4·H2O).
