Hazard InformationBack Directory
[General Description]

A colorless fuming liquid with a faint ammonia-like odor. Corresponds to a 64% aqueous solution of hydrazine in water. Combustible but may require some effort to ignite. Contact with oxidizing materials may cause spontaneous ignition. Toxic by inhalation and by skin absorption. Corrosive to tissue. Produces toxics oxides of nitrogen during combustion.
[Reactivity Profile]

HYDRAZINE HYDRATE(7803-57-8) is a base and a very powerful reducing agent. Very corrosive. Violent reaction on contact with alkali metals (sodium, potassium), 2,4-dinitrochlorobenzene, tin dichloride, mercury oxide. Vigorous neutralization reaction with acids. Emits toxic fumes of nitrogen oxides when heated to decomposition [Lewis, 3rd ed., 1993, p. 680]. Reacts with tin(II) chloride to give tin(II) dihydrazine chloride, which decomposes explosively when heated [Mellor 7:430(1946-1947)]. Reacts exothermically and violently with 2,4-dinitrochlorobenzene [Wischmeyer (1967)].
[Air & Water Reactions]

Fumes in air. Water soluble.
[Hazard]

See hydrazine.
[Health Hazard]

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
[Fire Hazard]

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Questions and Answers (Q&A)Back Directory
[Uses]

Hydrazine hydrate is used as a reducing agent in synthetic and analytical reactions and as a solvent for many inorganic compounds. It also is used with methanol as a propellant for rocket engines. Another application is catalytic decomposition of hydrogen peroxide.
[Preparation]

Hydrazine hydrate is prepared by treating hydrazine sulfate, N2H4•H2SO4 with sodium hydroxide. The product is collected by distillation under nitrogen. It also is obtained as a by-product in the Bayer Ketazine process for producing hydrazine in which hydrazine solution is hydrolysed under pressure in a ketazine column.
