Description
Refined naphthalene is a white crystalline solid derived from the distillation of coal tar or petroleum. It is primarily composed of fused benzene rings and is commonly used in the manufacturing of mothballs, as well as in the production of phthalic anhydride, which is used in the production of plastics. Here are some key points about refined naphthalene:
- Chemical Structure: Refined naphthalene has a chemical formula of C10H8, consisting of two benzene rings fused together. It is classified as a polycyclic aromatic hydrocarbon (PAH).
- Physical Properties: Refined naphthalene is a white, crystalline solid with a strong odor. It has a melting point of around 80°C (176°F) and a boiling point of around 218°C (424°F).
- Uses:
- Mothballs: Refined naphthalene is commonly used in the manufacturing of mothballs and moth flakes due to its insect-repellent properties.
- Chemical Industry: Refined naphthalene is used as a raw material in the production of various chemicals, including phthalic anhydride, which is used in the production of plastics, dyes, and resins.
- Concrete Admixtures: Refined naphthalene is used as a superplasticizer in concrete admixtures to improve workability and reduce water content.
- Veterinary Medicine: Refined naphthalene is used in some veterinary medicines as an anthelmintic (dewormer) for animals.
