Price and availability on request. Send us the quantity and delivery location in Oman.

Overview

Most common applications is in pharmaceuticals, water treatment, agrochemical, polymer etc

Product description

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.

Applications

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.

Industries and related products

Catalyzed Hydrazine Hydrate 35%

Catalyzed Hydrazine Hydrate 35% is an aqueous hydrazine-based chemical formulation used primarily in industrial water treatment and boiler-water applications, where hydrazine acts as an oxygen scavenger and helps control dissolved oxygen-related corrosion.

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.

Notes

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.
