About Crude Naphthalene
Crude Naphthalene (CAS 91-20-3) is recovered directly from the fractional distillation of coal tar, before the refining steps that remove sulphur compounds, thionaphthene, and other impurities. It is the primary industrial feedstock for the production of refined naphthalene and phthalic anhydride, and is also consumed directly in applications where reagent-grade purity is not required — including naphthalene sulfonate synthesis and moth repellent manufacturing. First Chemicals sources crude naphthalene from verified coal-tar processing facilities across Russia, Indonesia, India, and Europe, ensuring consistent supply with full documentation including COA and MSDS for each shipment.
Key Applications
- Feedstock for refined naphthalene production
- Phthalic anhydride (PA) manufacturing
- Naphthalene sulfonate superplasticizer production
- Moth repellent and naphthalene ball manufacturing
- Chemical synthesis intermediates
- Tanning and leather processing auxiliaries

Frequently Asked Questions
What is crude naphthalene?
Crude Naphthalene is an aromatic hydrocarbon (C₁₀H₈, CAS 91-20-3) recovered directly from coal tar distillation before further refining. It typically has a purity above 95% with sulphur content up to 1.5%, and is supplied as flakes or blocks.
What is the difference between crude and refined naphthalene?
Crude naphthalene is the raw distillate from coal tar containing sulphur compounds and other impurities (purity ~95%+). Refined naphthalene undergoes additional purification to achieve 99%–99.9% purity with very low sulphur, making it suitable for high-purity applications like phthalic anhydride and dye synthesis.
What are the main industrial uses of crude naphthalene?
Crude naphthalene is primarily used as feedstock for refined naphthalene and phthalic anhydride production. It is also used in naphthalene sulfonate superplasticizer manufacture, moth repellent production, and as a chemical intermediate in several downstream processes.
What countries does First Chemicals source crude naphthalene from?
First Chemicals sources crude naphthalene from verified facilities in Russia, Indonesia, India, and Europe, allowing us to offer competitive pricing and reliable supply across seasons.
What documentation is available with crude naphthalene shipments?
Each shipment comes with a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and full trade documentation including bill of lading and country-of-origin certificate.
