Part No: RXSOL-42-1541-235
Most common applications is in pharmaceuticals, water treatment, agrochemical, polymer etc
Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.
Hydrazine is mainly used as a foaming agent in preparing polymer foams.
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
Hydrazine hydrate traditional applications is in pharmaceuticals, water treatment, agrochemical, polymer and blowing agent and others, hydrazine hydrate is consumed in commercial applications such as rocket fuels also and other industries.

Important Safety Note
Hydrazine hydrate is highly toxic, corrosive and hazardous and can present significant health and fire risks. Catalyzed formulations require strict process controls. Handling, storage, dosing and transportation should be carried out only by trained personnel using the current SDS/TDS and applicable regulatory requirements.
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.

|
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. . |
| Advice on protection against fire and explosion | Keep away from sources of ignition - No smoking.Take measures to prevent the build up of electrostatic charge. |
| Incompatible materials | Keep away from alkalis, strong oxidizing agents and metals. Provide containment walls of adequate capacity to hold any accidental spills. |
