What Is Naphthalene?

Naphthalene is a polycyclic aromatic hydrocarbon composed of two fused benzene rings.

At normal ambient temperature, it is generally a crystalline solid with a characteristic aromatic odor and a melting point close to 80°C.

Commercial Naphthalene is commonly recovered during the processing and distillation of coal tar, although petroleum-derived Naphthalene is also available.

Crude Naphthalene contains Naphthalene together with other aromatic compounds and impurities. Through further refining and purification, the concentration of Naphthalene increases while impurity levels are reduced.

This produces different commercial grades suitable for different manufacturing processes.

For industrial buyers, the important parameters are not limited to purity alone. Depending on the application, manufacturers may also evaluate:

• Crystallization Point
• Thionaphthene Content
• Appearance
• Color
• Impurity Profile
• Physical Form

For this reason, selecting the correct Naphthalene grade should always be based on the actual production process and required technical specification.

We can provide the relevant COA for technical review before order confirmation, allowing customers to compare our available grades with their production requirements.

Refined Naphthalene vs Technical and Crude Naphthalene

Commercial Naphthalene can broadly be divided into Refined, Technical and Crude grades.

The main difference between these grades is the level of purification and the concentration of Naphthalene.

Refined Naphthalene

Refined or Pure Grade Naphthalene has the highest purity and the tightest impurity specifications.

It is generally selected for applications where consistent chemical quality and high Naphthalene concentration are important.

Our Pure Grade is available at:

Naphthalene Purity: Min. 99.5%

Technical Naphthalene

Technical Grade contains a slightly lower Naphthalene concentration and is suitable for many general industrial chemical processes.

It offers a practical balance between feedstock quality and commercial cost.

Our Technical Grade is available at:

Naphthalene Purity: Min. 97%

Crude Naphthalene

Crude Naphthalene contains more accompanying aromatic compounds and is mainly used where additional processing, refining or chemical conversion will take place.

Our Crude Grade is available at:

Naphthalene Purity: Min. 95%

Main Industrial Uses of Naphthalene

The primary commercial value of Naphthalene is as a chemical feedstock.

In most industrial applications, Naphthalene is chemically converted into another intermediate before becoming part of a finished product.

The main downstream industries include construction chemicals, resin manufacturing, dyes, pigments, textile chemicals and specialty chemicals.

Naphthalene for Phthalic Anhydride Production

One of the most established industrial applications of Naphthalene is the production of Phthalic Anhydride, commonly abbreviated as PA.

Naphthalene can be oxidized in an industrial process to produce Phthalic Anhydride.

The downstream production chain can be represented as:

Naphthalene → Phthalic Anhydride → Resins / Plasticizers / Coatings / Chemical Intermediates

Phthalic Anhydride is used in the manufacture of:

• Alkyd Resins
• Unsaturated Polyester Resins
• Plasticizer Intermediates
• Coating Raw Materials
• Dyes and Pigments
• Specialty Chemical Derivatives

For this type of production, feedstock purity and crystallization point can be important parameters.

For customers requiring high-purity material, we offer Pure Grade Refined Naphthalene 99.5% Min., with COA available for technical evaluation.

Naphthalene for SNF and Concrete Admixtures

Naphthalene is also a key raw material used in the production of Sulfonated Naphthalene Formaldehyde.

This material is commonly known as:

• SNF
• NSF
• PNS
• Polynaphthalene Sulfonate
• Naphthalene-Based Superplasticizer

The general production route involves the sulfonation of Naphthalene followed by further reaction and condensation.

A simplified process is:

Naphthalene → Naphthalene Sulfonic Acid → SNF / PNS → Concrete Admixture

SNF is widely used as a concrete superplasticizer and high-range water-reducing agent.

It helps improve the dispersion of cement particles, allowing better concrete workability while controlling water demand.

Typical downstream applications include:

• Ready-Mix Concrete
• Precast Concrete
• High-Strength Concrete
• Concrete Admixtures
• Construction Chemicals
• Cement Formulations

Manufacturers of SNF, PNS and concrete admixtures therefore represent an important customer segment for Naphthalene.

Depending on the customer’s formulation, Technical Grade 97% or higher-purity Refined Naphthalene may be evaluated.

We supply both grades for industrial customers requiring bulk material for Naphthalene sulfonation and downstream chemical production.

Naphthalene for Dyes and Pigments

Naphthalene is an important starting material in organic chemical synthesis and can be converted into various intermediates used in dye and pigment manufacturing.

Naphthalene derivatives can be involved in the production of:

• Azo Dyes
• Textile Dyes
• Pigment Intermediates
• Naphthols
• Naphthalene Sulfonic Acids
• Aminonaphthalene Derivatives
• Specialty Color Chemicals

In these production processes, the quality of the feedstock can affect downstream reaction consistency and final product quality.

For this reason, manufacturers of dye intermediates may require higher-purity grades with controlled impurity levels.

Our Pure Grade 99.5% is available for customers requiring tighter specifications, while Technical Grade may also be suitable depending on the production route.

Naphthalene for Textile Chemicals

Naphthalene also serves as an upstream raw material for the production of certain textile auxiliaries and dispersing agents.

Naphthalene itself is generally not used directly in textile products.

Instead, it is chemically converted into derivatives that can be used in:

• Dye Dispersants
• Textile Auxiliaries
• Wetting Systems
• Pigment Dispersion
• Textile Processing Chemicals

Manufacturers involved in Naphthalene sulfonation and textile chemical production can source suitable Technical or Refined grades according to their required specification.

Naphthalene for Industrial Dispersants

Sulfonated Naphthalene derivatives are widely valued for their dispersing properties.

They can help maintain particles in suspension and improve dispersion in liquid systems.

Typical applications include:

• Industrial Dispersants
• Pigment Dispersants
• Concrete Admixture Dispersants
• Textile Dispersants
• Specialty Chemical Formulations

This makes Naphthalene an important feedstock for chemical manufacturers producing Naphthalene-based dispersing agents.

Naphthalene for Resins and Coatings

Naphthalene also plays an indirect role in resin and coating manufacturing.

A major example is its conversion into Phthalic Anhydride, which can then be used to manufacture different resin systems.

The value chain may include:

Naphthalene → Phthalic Anhydride → Resin → Coating / Paint / Industrial Formulation

This is why Naphthalene is considered an important upstream raw material for various resin and coating related chemical processes.
