Refined Naphthalene, identified by its CAS Number 91-20-3 and chemical formula C10H8, stands as the most crucial condensed cyclic hydrocarbon within the chemical industry. This high-purity material is typically a white crystalline powder, exhibiting excellent stability and consistent quality, with a typical naphthalene content exceeding 99.4% and a crystallization point around 79.8°C.

The primary application of refined naphthalene globally is its conversion into phthalic anhydride. While o-xylene also serves as a precursor, naphthalene remains a significant feedstock for this essential chemical, which is widely used in the production of plasticizers, unsaturated polyester resins, and alkyd resins. However, the utility of refined naphthalene extends far beyond this single application, making it a versatile intermediate for numerous downstream products.

One significant area of application is the dye industry. Many azo dyes, which are integral to the coloring of textiles and other materials, are synthesized using naphthalene derivatives. Intermediates such as various naphthols, naphthylamines, and particularly aminonaphthalenesulfonic acids, are derived from naphthalene and are vital components in creating a wide spectrum of synthetic dyes.

Furthermore, refined naphthalene plays a critical role in the agricultural chemical sector. It serves as a raw material for producing insecticides like 1-naphthyl-N-methylcarbamate (commonly known as carbaryl) and various naphthoxyacetic acids, which function as plant growth regulators. Its derivatives also find use in the pharmaceutical industry and in the production of perfumes.

Naphthalenesulfonic acids and their salts, particularly alkyl naphthalene sulfonates (ANS), are highly valued for their surfactant properties. These non-detergent wetting agents are remarkably effective at dispersing colloidal systems in aqueous solutions. Their industrial applications are extensive, including use in the agricultural sector for formulating wettable powders and granular formulations, and in the textile industry where their wetting and defoaming capabilities are beneficial in bleaching and dyeing processes.

Beyond these major uses, refined naphthalene contributes to other diverse applications. It is utilized in the manufacture of synthetic resins, plasticizers, synthetic fibers, coatings, and as raw material for rubber additives. Niche applications include its use in pyrotechnics to generate effects like black smoke or simulated explosions, and in manufacturing high-porosity grinding wheels by creating artificial pores.

Sourced from China, refined naphthalene is typically packaged in 25 Kg Bags, providing convenient handling for industrial use.
