Refined Naphthalene: A Crucial Intermediate for Global Industries

NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight the availability of its high-purity Refined Naphthalene (CAS 91-20-3). This versatile chemical, derived primarily from the meticulous distillation of coal tar, stands as a cornerstone building block in numerous industrial processes worldwide. Presented as a white, crystalline powder or flake, Refined Naphthalene possesses a distinctive, characteristic odor and boasts exceptional purity levels, making it indispensable for demanding applications.

With the chemical formula C10H8, Refined Naphthalene has a long history of use as a fundamental aromatic hydrocarbon. Its stable structure and reactive sites enable its transformation into a wide array of downstream products. The consistent quality and high purity offered by NINGBO INNO PHARMCHEM CO.,LTD.'s Refined Naphthalene, demonstrated by a typical crystallization point of 79.88°C and a naphthalene content often exceeding 99.45%, are crucial for achieving optimal results in sensitive synthesis and production processes.

Diverse Applications Driving Demand

The primary application of Refined Naphthalene is its conversion into phthalic anhydride, a process that accounts for approximately 70% of the global consumption of this valuable intermediate. Phthalic anhydride itself is a key precursor for manufacturing plasticizers, polyester resins, and alkyd resins, which are integral to the production of plastics, coatings, and construction materials. The reliability and purity of the initial naphthalene feedstock directly impact the efficiency and quality of phthalic anhydride production, underscoring the importance of sourcing from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD.

Beyond phthalic anhydride, Refined Naphthalene serves critical roles in several other significant industries:
- Dye and Pigment Manufacturing: Naphthalene derivatives are essential components in the synthesis of various dyes and pigments, providing vibrant colors for textiles, paints, inks, and plastics. The purity of the naphthalene is vital to ensure color consistency and intensity.
- Surfactant Synthesis: Alkyl naphthalene sulfonates derived from Refined Naphthalene are effective wetting agents and dispersants used in agricultural formulations, textile processing, and detergent production. Their performance relies heavily on the quality of the naphthalene base.
- Rubber Antioxidants: Refined Naphthalene is a key intermediate in the production of rubber antioxidants, such as TMQ (2,2,4-trimethyl-1,2-dihydroquinoline polymer). These antioxidants protect rubber products from degradation due to oxidation, extending their lifespan and performance in applications ranging from tires to industrial belts.
- Pharmaceutical Intermediates: Certain pharmaceutical compounds, including some sulfonamide drugs, utilize naphthalene derivatives in their synthesis. The stringent purity requirements for pharmaceutical manufacturing necessitate high-grade raw materials like Refined Naphthalene.
- High-Performance Concrete Plasticizers: Naphthalene sulfonates are employed as superplasticizers or high-range water reducers in concrete mixtures. They improve workability, reduce water content, and enhance the strength and durability of concrete structures, which is essential for modern construction projects.

The steady growth observed in the global market for refined naphthalene is a testament to its continued importance and versatility across these diverse sectors. Industries rely on a consistent supply of high-quality material to meet production demands and maintain product integrity.

Quality and Safety Considerations

Ensuring the quality and safety of Refined Naphthalene handling and storage is paramount. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict quality control protocols to provide a product with minimal impurities, as evidenced by low ash content and non-volatile matter. However, due to its inherent properties, proper safety measures are essential. Refined Naphthalene is flammable with a flash point of 79°C and exhibits sublimation characteristics. Potential health effects, including the risk of hemolytic anemia, must be considered.

Recommended storage conditions include maintaining temperatures below 30°C in sealed containers to prevent sublimation and maintain product integrity. Facilities handling Refined Naphthalene should utilize explosion-proof electrical equipment and implement proper ventilation systems to mitigate risks associated with its flammability and vapor properties. Adherence to safety data sheets and best practices is always advised.
