Naphthalene （CAS 91-20-3）

Naphthalene (CAS 91-20-3) Basic characteristics and supply guarantee Naphthalene (CAS 91-20-3) is a white crystalline aromatic hydrocarbon with a special odor and stable chemical properties. As a senior Chinese naphthalene supplier, we focus on providing high-quality naphthalene products. From raw material screening to production and processing, we follow strict standards to ensure controllable quality and stable performance of each batch of products, meeting the basic needs of various industrial scenarios.

 

The industrial grade naphthalene we supply has high purity, low impurity content, good crystallinity, and moisture content controlled below 0.5%. The product has stable physical indicators such as melting point and boiling point, excellent thermal stability, and is not easily hygroscopic or clumped during storage and transportation. It can adapt to different climatic conditions in different regions and provide reliable raw material support for industrial production.

Naphthalene tablets are our main supply form, with regular tablet shapes and uniform sizes, making them easy to measure and use. The product adopts moisture-proof packaging, with an inner layer of plastic film bag and an outer layer of woven bag or iron drum, which can effectively isolate moisture and impurities. Standardizing the weight of each bag/barrel (such as 25kg/50kg) not only facilitates handling, but also reduces losses during storage, ensuring that the product remains in optimal condition when it reaches the customer's hands.

As a professional Chinese naphthalene supplier, we can achieve stable supply on a large scale and quickly respond to customers' bulk order demands.

Naphthalene (CAS 91-20-3) is an important chemical raw material with wide applications in the chemical industry. Through oxidation reaction, naphthalene can generate phthalic anhydride, which is a key raw material for the production of plasticizers, polyester resins, alkyd resins, etc. Plasticizers made from phthalic anhydride can effectively improve the flexibility and processability of plastics, and are widely used in plastic products such as polyvinyl chloride. Polyester resin and alkyd resin play an important role in the fields of coatings, adhesives, etc., providing good performance support for related products. In addition, naphthalene can also be used to produce naphthol, which is an important intermediate for synthesizing various organic compounds and occupies an important position in chemical synthesis.

In the dye and pigment industry, naphthalene (CAS 91-20-3) is one of the indispensable raw materials. Various dyes can be synthesized using naphthalene as the basic raw material, such as acid dyes, direct dyes, dispersed dyes, etc. Acid dyes are suitable for dyeing protein fibers such as wool and silk, which can give fabrics bright colors and good fastness; Direct dyes can be directly used for dyeing cellulose fibers such as cotton and linen, with simple operation and low cost; Disperse dyes are mainly used for dyeing synthetic fibers such as polyester, and have excellent dyeing effects. At the same time, naphthalene derivatives can also be used to produce pigments, providing rich color sources for products such as inks and coatings.

Naphthalene (CAS 91-20-3) has certain applications in the pharmaceutical field, and its derivatives can be used to synthesize certain drugs. For example, naphthol compounds play an important role in the synthesis of some antibacterial and anti-inflammatory drugs, providing a key chemical structural basis for drug development. In terms of hygiene products, naphthalene has insecticidal properties and can be used to make sanitary balls (mothballs), which can effectively drive away pests during clothing storage and protect clothing from insect damage. It is a commonly used household hygiene protective product.

Naphthalene (CAS 91-20-3) can be used as a raw material for plant growth regulators in the agricultural field. Its derivatives can promote plant growth, increase crop yield, regulate crop growth cycles, and enhance crop stress resistance. In terms of industrial additives, naphthalene can be used to produce water reducers, which can improve the fluidity and plasticity of concrete in concrete engineering, reduce water consumption, and enhance the strength and durability of concrete. In addition, naphthalene can also be used to synthesize industrial additives such as lubricants and mineral processing agents, playing an auxiliary role in industries such as machinery manufacturing and mineral processing, improving production efficiency and product quality.
