Naphthalene

Description:
Naphthalene, with the CAS number 91-20-3, is a polycyclic aromatic hydrocarbon consisting of two fused benzene rings. It appears as a white crystalline solid at room temperature and has a characteristic odor reminiscent of mothballs. Naphthalene is insoluble in water but soluble in organic solvents such as ethanol, ether, and benzene. It has a melting point of around 80 degrees Celsius and a boiling point of approximately 218 degrees Celsius. Naphthalene is primarily used in the production of phthalic anhydride, as a precursor for various chemicals, and as a moth repellent. It is also found in some air fresheners and deodorants. Due to its aromatic structure, naphthalene exhibits significant volatility and can sublimate at room temperature. While it is considered a relatively low-toxicity compound, exposure can lead to health issues, including respiratory irritation and hemolytic anemia in severe cases. Naphthalene is classified as a possible human carcinogen, necessitating careful handling and regulation in industrial applications.
