Physical properties of hydrazine hydrate

ATTENTION!!!: a product with a mass fraction of hydrazine hydrate of 64% and a hydrazine content of 41% has appeared on the Russian market. This product has nothing in common with GOST (according to GOST 19503-88. Test section, P.1 - the content of the main substance hydrazine should be 64% + -0.5% gives an analysis error).

GOST does not allow other concentrations of hydrazine. Accordingly, the use of the product in Russia is unacceptable. Be careful!!!

Explosion and fire hazard

Hydrazine hydrate is a flammable liquid that forms explosive mixtures with air and O2; in air, upon contact with catalytically active substances that have a developed surface (sand, earth, asbestos, activated carbon, cotton wool, yarn, oxides of Cu, Fe, Hg, etc.) it is prone to spontaneous combustion. Easily ignites from sparks and flames. In air, the flash point is 270°C (in pure O2 and in the presence of metals and their oxides the flash point decreases), the ignition temperature is not lower than 73°C, the concentration limit of flame propagation in volume fractions: lower 7.3%, upper 100%.

Containers may explode when heated. In empty containers, explosive mixtures can form from residues. Burns with the formation of toxic gases (cyanine, nitrogen oxides). A flammable concentration of vapors forms above the surface of the spilled liquid at ambient temperatures equal to the flash point of the liquid or higher.

Danger to humans

It is highly toxic, irritates the mucous membranes, eyes and respiratory tract, affects the central nervous system and liver, if it gets on the skin, it causes eczema.

Dangerous if inhaled (cough, chest pain, respiratory distress, increased heart rate, loss of consciousness), contact with skin (redness, dryness, itching), contact with eyes (soreness, lacrimation). Acts through intact skin. Chemical burn. Fires and explosions may cause burns and injuries.

Hydrazine hydrate is an inorganic compound Hydrazine hydrates with the formula N2H4•H2O. It is also called diamide hydrate. Prepared by reacting sodium hypochlorite NaClO with ammonia (NH3) or urea (CO(NH2)2).

Properties

Heavy “smoking” liquid, colorless, with a pronounced ammonia odor. At temperatures below -65 °C - cubic crystals, white, ammonia odor is not strong. The substance is prone to spontaneous combustion at temperatures above +75 °C. Vapors are heavier than air and can explode when mixed with air. The reagent is highly soluble in water and alcohols in any proportions, slightly soluble in hydrocarbons, and insoluble in chloroform, benzene, and ethers. It is hygroscopic and actively interacts with carbon dioxide and oxygen in the air. Extremely poisonous. Decomposes in light and when heated into ammonia, hydrogen, nitrogen, sometimes explosively. It burns, but poorly. Impact resistant. Easily decomposes in the environment.

Diamide hydrate is a chemically stable compound that actively reacts with many substances (more active than ammonia), a strong reducing agent, and acts as a weak alkali in reactions. It has corrosive properties towards glass, rubber, metals and their oxides. Reaction with acids leads to the formation of salts. Interacts with oxygen and carbon dioxide. When exposed to dehydrating agents, the hydrate is converted to the highly toxic and less stable hydrazine.

Precautions

Belongs to hazard class 1. In contact with skin or mucous membranes, the substance or its vapors are highly irritating. Possible chemical burns, dermatitis, allergic reactions, damage to the nasopharyngeal mucosa when inhaling vapors or “fog,” and damage to vision. It is a poison that affects the hematopoietic system and liver, and a carcinogen. All work with the reagent should be carried out either in a fume hood, or in a room with general and local exhaust ventilation, wearing a respirator, safety glasses and specially designed chemical protective clothing.

Disposal should be entrusted to specialized organizations and companies. If diamide hydrate comes into contact with your skin, wash it with soap and water and do not pour the water down the drain. The reagent can be removed from waste water using activated carbon and copper-based catalysts. The substance is especially dangerous for the inhabitants of water bodies.

Hydrazine hydrate is stored in unheated warehouses, away from heat sources, sunlight, oxidizing agents and flammable materials, in sealed containers made of corrosion-resistant steel, aluminum, and plastic. The covers must have Teflon gaskets. Filling - no more than 90%, since during storage the reagent can decompose with the release of gases, which can even lead to an explosion. All containers must be marked with danger signs, name and date of manufacture.

If diamide hydrate comes into contact with a fire, it should be extinguished only with water.
