Remarks / Precaution

Hydrazine hydrate mainly used as:

Organic synthesis intermediates for agrochemicals, pharmaceuticals, manufecturing of chemicals, etc

Laboratory reagent in fine chemicals

Reducing agent in metals purification of precious metals in the mining industry, etc

Oxygen scavenger on ultra high pressure industrial sites

Blowing agent for polymer (PE, PVC, PMMA, EVA, rubber, etc) foams

Note

Hydrazine is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings. The test for hydrazine can be controlled by http://rxmarine.com/hydrazine-test-kit in which several solutions have been formulated into a single, stable reagent. The method is both sensitive and easy to perform. It is used mostly for the determination of small amounts of hydrazine in boiler feedwater. There are no common interferences.

The establishment of protective metal oxide layers through the use of reducing agents (such as hydrazine, hydroquinone, and other oxygen scavengers) is known as metal passivation or metal conditioning. Although "metal passivation" refers to the direct reaction of the compound with the metal oxide and "metal conditioning" more broadly refers to the promotion of a protective surface, the two terms are frequently used interchangeably.

The reaction of hydrazine and hydroquinone, which leads to the passivation of iron-based metals, proceeds according to the following reactions:

N₂H₄	+	6Fe₂O₃	®	4Fe₃O₄	+	2H₂O	+	N₂
hydrazine		hematite		magnetite		water		nitrogen

C₆H₄(OH)₂	+	3Fe₂O₃	®	2Fe₃O₄	+	C₆H₄O₂	+	H₂O
hydroquinone		hematite		magnetite		benzoquinone		water

Similar reactions occur with copper-based metals:

N₂H₄	+	4CuO	®	2Cu₂O	+	2H₂O	+	N₂
hydrazine		cupric oxide		cuprous oxide		water		nitrogen

C₆H₆O₂	+	2CuO	®	Cu₂O	+	C₆H₄O₂	+	H₂O
hydroquinone		cupric oxide		cuprous oxide		benzoquinone		water

Magnetite and cuprous oxide form protective films on the metal surface. Because these oxides are formed under reducing conditions, removal of the dissolved oxygen from boiler feedwater and condensate promotes their formation. The effective application of oxygen scavengers indirectly leads to passivated metal surfaces and less metal oxide transport to the boiler whether or not the scavenger reacts directly with the metal surface.

A significant reduction in feedwater oxygen and metal oxides can occur with proper application of oxygen scavengers.

Indication of any immediate medical attention and special treatment needed	No data available

Flammability	Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Suitable extinguishing media	Water is the preferred extinguishing media as it will dilute the material resulting in a non-flammable mixture. Use alcohol resistant foam, carbon dioxide, dry chemical, or vaporizing liquid extinguishing agents. Water spray or fog may also be effective for extinguishing or to absorb heat and keep exposed material from being damaged by fire.
Unsuitable extinguishing media	Not Available

Specific Hazards Arising from the Chemical	Oxides of phosphorus Sodium oxides Not combustible. Fire may cause evolution of: Oxides of phosphorus Ambient fire may liberate hazardous vapours.

Personal precautions, protective equipment and emergency procedures	Wear appropriate personal protective equipment. Ventilate area. Only enter area with PPE. Stop or reduce leak if safe to do so. Prevent material from entering sewers. Flush with water to remove any residue.
Spillage	Oxidizing material. Stop leak if without risk. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance damp using water spray. Do not touch spilled material. Prevent entry into sewers, basements or confined areas dike if needed. Eliminate all ignition sources. Call for assistance on disposal.
Enviromental Precaution	This material is miscible in water. Notify all downstream users of possible contamination. Divert water flow around spill if possible and safe to do so.
Methods and materials for containment and cleaning	Spills should be contained by diking and digging a containment pit sufficiently large enough to hold at least 10 times the spill. Dilute to approximately 10 times the volume with water and add 5-8% calcium hypochlorite solution slowly to completely oxidize the hydrazine. Dry calcium hypochlorite or other oxidizing agents should never be allowed to mix with undiluted hydrazine solutions. The resulting reaction is very vigorous, releasing large amounts of heat and hydrogen gas. Neutralized material can be absorbed using clay, sand or commercial absorbent and place material into containers for future disposal per local regulations. .
