Nitric acid fuming 98% is a highly concentrated and reactive chemical widely used in industrial and laboratory processes. At Maruti Fine Chemicals, we supply premium-grade nitric acid fuming tailored to meet the stringent requirements of chemical manufacturing, metallurgy, and the pharmaceutical sector.

What is Nitric acid fuming 98%?

Nitric acid fuming 98% is a concentrated form of nitric acid with an approximate 98% HNO3 composition and elevated nitrogen dioxide content. It has a strong oxidizing capability and emits reddish-brown fumes, hence the term "fuming."

It is often categorized into two types:

1.Red Fuming Nitric Acid (RFNA) – Contains higher nitrogen dioxide and is more reactive.

2.White Fuming Nitric Acid (WFNA) – Purified to remove nitrogen oxides and appears as a colorless or pale yellow liquid.

Industrial Applications

1. Aerospace and Rocket Propellants

One of the most notable applications of nitric acid fuming is in the aerospace industry, where it serves as an oxidizing agent in liquid rocket propellants. Its reactivity and high energy density make it essential for achieving efficient thrust.

2. Pharmaceutical Manufacturing

In pharmaceutical labs, nitric acid fuming is used to synthesize intermediates and active pharmaceutical ingredients (APIs). It acts as both a nitrating and oxidizing agent in complex organic reactions.

3. Explosives and Munitions

Nitric acid fuming is integral to the production of explosives like nitroglycerin and trinitrotoluene (TNT). Its ability to nitrate organic compounds enables the synthesis of high-energy explosives.

4. Etching and Metal Treatment

Industries dealing with metal processing use nitric acid fuming for etching metals and cleaning surfaces. It is highly effective in removing oxides and impurities, especially in stainless steel treatment.

5. Chemical Synthesis

Various industrial chemical reactions require nitric acid fuming for introducing nitro groups into organic molecules. This is a common step in manufacturing dyes, synthetic fibers, and agrochemicals.

Key Properties

1. High Reactivity – Capable of initiating violent oxidation reactions.

2. Corrosive Nature – Can corrode metals, skin, and tissue upon contact.

3. Fuming Behavior – Emits reddish fumes when exposed to air.

4. Water-Sensitive – Reacts exothermically with water, releasing toxic gases.

5. Unstable in Open Air – Requires sealed and specialized storage containers.

Handling and Safety Measures

Due to its aggressive and hazardous nature, Nitric acid fuming 98% should be handled with utmost caution:

1.Personal Protective Equipment (PPE) – Use acid-resistant gloves, face shields, and protective clothing.

2.Ventilation – Ensure proper fume hoods or exhaust systems are in place to prevent exposure.

3. Storage – Store in tightly sealed, corrosion-resistant containers away from heat and moisture.

4.Emergency Readiness – Have neutralizing agents like sodium bicarbonate and safety showers readily accessible.

Environmental Considerations

Because nitric acid fuming releases nitrogen oxides, it has significant environmental implications if not handled responsibly. Spills or leaks must be immediately contained and neutralized. We promote responsible handling and disposal protocols to protect both personnel and the environment.

Frequently Asked Questions (FAQs)

Q1. What should I do in case of skin contact with this chemical?

Immediately rinse the affected area with copious amounts of water for at least 15 minutes. Remove any contaminated clothing and seek medical attention promptly.

Q2. Can this chemical be mixed with water?

 It should never be directly mixed with water, as it can lead to an exothermic reaction, releasing harmful gases. Always follow standard dilution procedures and safety protocols.

Q3. What industries commonly use this substance?

It is extensively used in aerospace, pharmaceuticals, explosives, metal treatment, and chemical synthesis.

Q4. How should it be stored safely?

It should be stored in tightly sealed, corrosion-resistant containers in a cool, dry, and well-ventilated area away from incompatible materials.

Q5. Is it environmentally hazardous?

Yes, improper disposal or spillage can cause significant harm to the environment. Disposal must follow local regulatory guidelines.

Q6. What precautions should be taken during transportation?

Transportation should be conducted in compliance with hazardous materials regulations using approved containers and trained personnel.

Q7. Can it be used in laboratory experiments?

Yes, but only under strict supervision and within controlled environments equipped with appropriate safety measures.

Q8. What are the physical signs of exposure?

Exposure may cause coughing, shortness of breath, skin burns, and eye irritation. In severe cases, it can lead to respiratory distress.

Q9. Is it reactive with metals?

Yes, it can corrode various metals and should not come in contact with metal surfaces unless specifically designed for chemical compatibility.
