Hydrazine Hydrate

What is Hydrazine Hydrate

Hydrazine Hydrate is one of the fuming, oily liquids, having no color. In terms of odor, it has similarity to ammonia. One can dissolve it in alcohol and water. However, in ethyl ether and chloroform, this Hydrazine Hydrate is insoluble.

Hydrazine Hydrate is used in fungicides and herbicides manufacturing, it is highly valuable ingredient. Other sectors, where we have found its use, include pharmaceuticals (tuberculosis drugs) and tranquilizers). At present, plastic industries also rely on Hydrazine Hydrate for creating the polymerization initiators and various blowing components.

The strength of Hydrazine Solution depends on the percentage of Hydrazine in the solution. The mixture of Hydrazine and Water together forms monohydrate – N2H4.H20. It occurs due to the bonding of hydrogen. Therefore, it can be said that the percentage of Hydrazine in a solution is equivalent to the percentage of Hydrazine Monohydrate. The relationship between the two depends on their molecular weights.

The molecular weight of Hydrazine us 32 and that of Monohydrate is 50. The ratio between the two depending on their weights is 32/50 or 0 .64. Monohydrate in it’s 100% form contains 32/50 or 64% of Hydrazine. This means that a solution by weight of 100% of Hydrazine Hydrate can be used interchangeably with 64% Hydrazine.

INDUSTRIAL APPLICATIONS

Agriculture.
Today’s agriculture needs crop protection agents that can help to take care of the pests, weeds, insects and other micro-organisms. Hydrazine is present in the best crop protection chemicals. This provides the world with food that is healthy. Hydrazine has the power to enter reactions and take care of active compounds.

Chemical Blowing Agents.
CBAs also called Foaming Agents are used in plastic processes. The benefits of this includes reduction in polymer density, saving material costs, improvement in electrical as well as insulative properties and the increase in the ratio of strength to weight. Products like food container, core pipe, vinyl sheets, furniture, etc uses foamed plastic. CBA is basically used for the processing of medium temperature polymer. Polystyrene, polypropylene, polyethylene, PVC and ABS uses azodicarbonamide.

Benzene and Toluenesulfonylhydrazide are also CBAs which are used for lower temperature application. Oxybis Benzenesulfonyl Hydrazide, although made with Hydrazine requires high temperature to decompose.

Water Treatment.
By removing the cause of corrossion in boilers with the use of Hydrazine products a lot of money and time can be saved. The product we suggest can protect the boiler and can be used for closed circulating hot water heating systems.

Other Applications.
Urethanes.
In order to crosslink the polymers Hydrazine is mixed with urethane solutions. Hydrazine is both nucleophilic and bi-functioal. This causes rapid reaction with isocyanates and acrylates. Crosslink helps to improve the durability and strength of the plastics.

Lubricants.
Lubricant Additives mostly use dimercaptothiadiazole which is a Hydrazine based sulfur compound.

Antioxidants.
Hydrazine Moiety works as a reducing agent and is found in antioxidants and metal deactivator compounds.

Reducing Agents.
Hydrazine is used in the production of mirrors, recovery of precious metals and reduction of noble metals because it is powerful and acts rapidly as a reducing agent. No byproducts are left behind from the reaction of Hydrazine.

Miscellaneous
Hydrazine is needed in the production of flame retardants, iodine compounds and purification of muriatic acid.

Pharmaceuticals
Hydrazine is the main component used by the leading pharmaceutical of the world. Hydrazine is used because it is highly reactive and can enter several reactions causing biological active compounds. Triazine, Pyridazine, Triazole, Thiadiazole, and Pyrazole are used frequently by pharmaceuticals and uses Hydrazine.

Hydrazine Hydrate

Hydrazine Hydrate completely miscible with water, reacts with oxygen to form nitrogen and water.
In various Chemical sectors this hydrazine is applicable for herbicide ,sterilant and Insecticides.

INDUSTRIAL APPLICATIONS

Hydrazine Hydrate

We can use hydrazine anytime- at the time of lay-up or at the time for startup, while the boiler operates fully. We have presented one of those instances.

Passivation after cleaning

You can find acid cleaned boilers in the present age. However, in the old systems also, this cleaning process is useful for the removal of scales. It can eliminate the magnetite, accumulated in the old systems. While there is no magnetite, corrosion will come up on the steel-made surfaces. Thus, passivation is essential at the right time- during the startup. The circulation of deionized water that has hydrazine accomplishes the process. Ammonia may also be used.

Shutdowns and wet layups

While it is a wet layup, hydrazine offers a good safeguard against corrosion. Deionized water, having hydrazine (minimum 200 ppm) gets into the gaps and remains as residue on our equipment.

Hydrazine usage for this layup causes the interior surface to remain and adds purity to water. It is also useful for non-drainable tube storage. The reason behind it is that the solids, deposited, are not tolerable.

You can use hydrazine for having protection against corrosion in the steam generator, including the boiler and preheater. You may also use it in closed hot water heater.

Feed water and preheat protection-

For preheating system and for securing the fed water, you can feed hydrazine the deaerators’ storage units. The rust level gets lowered in these parts, and it decreases the iron amount in feedwater. It is helpful for making equipment long-lasting and for reducing the residues on the surface, transferring heat.

Boiler drums and tubes-

The boiler tube and drum corrosion is preventable with the maintenance of hydrazine residuals (ranging from 0.03 ppm to 0.50 ppm. The residue of sodium sulfite can be 10-60 ppm. However, the amount of residuals gets lowered due to higher pressure.

Steam and condensate systems-

The dissolved oxygen amount, pH level and dissolved solid amount- these are the major factors for smooth operation. Hydrazine acts as the best component for controlling the rust of condensate unit. Some limited vapor of hydrazine can get into steam, on the basis of the amount of residuals, present in boiler. The condensate unit will become secure by treating boiler water with hydrazine. However, there will be no presence of sodium sulfite in the steam. The FDA rules state that hydrazine must not be passed into steam while the edible products have a contact with steam.

Hot water heating-

For those, who are looking for the best corrosion inhibitor, Hydrazine is the right option. There is a particular dosage that causes hydrazine concentration to reach 50 ppm. It controls mild copper and steel corrosion in a lab at 170°F.
