Nitric acid fuming 98% is an ultra-concentrated grade of nitric acid (HNO₃) containing minimal water and extremely high oxidising power. Because of its high purity and reactivity, it’s widely used in advanced chemical synthesis, nitration, oxidation, and refining processes.

This grade, also known as white or red fuming nitric acid, emits visible nitrogen dioxide (NO₂) vapours due to the presence of dissolved nitrogen oxides. Its density is typically around 1.50 g/cm³, and its low water content makes it far more aggressive and reactive than standard nitric acid.

At Maruti Fine Chemicals, we supply high-purity fuming nitric acid 98% to ensure maximum yield, consistent performance, and reliable supply for industrial users who need precision and safety.

Q2. Why do industries prefer Nitric Acid Fuming 98% over standard nitric acid?

The key lies in performance. Standard nitric acid (60–70%) contains significant water, which can cause side reactions or reduce nitration efficiency. By contrast, Nitric Acid Fuming 98% offers ultra-high concentration, improving selectivity and yield in nitration and oxidation reactions.

Applications include:

1. Nitration of aromatic compounds

2. Production of high-energy materials and specialty organics

3. Metal purification and etching

4. Research and fine-chemical synthesis

In processes where every fraction of yield matters, switching to fuming nitric acid 98% reduces water interference and delivers cleaner, faster reactions.

Q3. Is handling Nitric Acid Fuming 98% risky?

Yes — it’s a highly corrosive and reactive acid. That’s why Maruti Fine Chemicals provides complete safety documentation, technical guidance, and compliant packaging under UN2031 classification.

Storage and handling require:

1. Inert, moisture-free containers

2. Corrosion-resistant tanks

3. Proper ventilation and fume control systems

4. Personal protective equipment (acid-resistant gloves, goggles, face shields)

Our logistics and safety team ensure every delivery meets global safety and regulatory standards. With us, you get high performance — without the hazard headaches.

Q4. What exactly is Fuming Sulphuric Acid, and how does it differ from regular H₂SO₄?

Fuming Sulphuric Acid, also known as Oleum, is sulfuric acid saturated with sulfur trioxide (SO₃). This dissolved SO₃ gives it extreme reactivity and the characteristic white fumes when exposed to air or moisture.

While regular sulphuric acid (98%) is already strong, fuming sulphuric acid is far more powerful in dehydration and sulfonation. It drives reactions that standard H₂SO₄ cannot, making it vital in:

1. Sulfonation of dyes, detergents, and specialty chemicals

2. Dehydration reactions in pharmaceuticals and intermediates

3. Petrochemical refining and advanced material synthesis

Maruti Fine Chemicals supplies oleum in controlled, moisture-free packaging with clear technical specifications and COAs for safe use and predictable results.

Q5. What makes Fuming Sulphuric Acid “fume”?

The “fuming” effect occurs because of the high SO₃ content. When exposed to air, SO₃ reacts with moisture, releasing white vapours — a clear indicator of its reactive nature. This intense reactivity allows Fuming Sulphuric Acid to act as a strong dehydrating and sulfonating agent.

It’s indispensable for industries that demand ultra-high reaction strength and efficiency. However, this same reactivity requires strict handling and proper safety measures — something Maruti Fine Chemicals is well-equipped to support.

Q6. How do Nitric Acid Fuming 98% and Fuming Sulphuric Acid complement each other?

These two reagents are often used together in advanced chemical reactions. For instance:

1. In nitration chemistry, a mixture of fuming nitric acid 98% and fuming sulphuric acid (oleum) is used to achieve superior nitration of aromatic compounds.

2. Nitric acid provides the nitrating strength, while sulphuric acid acts as the dehydrating medium that enhances reaction efficiency.

This combination is common in industries producing dyes, explosives, pharmaceuticals, and fine chemicals. Procuring both reagents from Maruti Fine Chemicals ensures consistent purity, simplified logistics, and uniform performance across your processes.

Q7. What are the safety standards followed by Maruti Fine Chemicals?

Q8. How can these reagents improve manufacturing efficiency?

Using Nitric Acid Fuming 98% and Fuming Sulphuric Acid can dramatically improve:

1. Reaction yield: Higher concentration means fewer impurities and side-products.

2. Selectivity: Cleaner reaction pathways, especially in nitration and sulfonation.

3. Throughput: Shorter reaction times and better conversion rates.

4. Process safety: Consistent reagent quality reduces unexpected reactions.

Even though the upfront cost is higher, the long-term gains in productivity, purity, and reduced downtime easily justify the investment.

Q9. What should manufacturers consider before switching to fuming-grade acids?

A practical guide:

1. Assess process limitations: Are you facing low yields or side reactions with standard acids?

2. Match reagent to process: Use Nitric Acid Fuming 98% for nitration/oxidation and Fuming Sulphuric Acid for sulfonation/dehydration.

3. Ensure equipment compatibility: Reactors, pipelines, and valves should be made of corrosion-resistant materials (glass-lined steel, PTFE, or special alloys).

4. Plan for safety: Install fume scrubbers, PPE protocols, and emergency wash stations.

5. Source from experts: Maruti Fine Chemicals provides not only the acid but also safety training, compliance, and handling guidance.

Q10. How should Nitric Acid Fuming 98% and Fuming Sulphuric Acid be stored?

Storage best practices:
