Naphthalene
Naphthalene (pronounced: /ˈnæf.θəˌliːn/, /ˈnæf.thəˌliːn/) is a simple polycyclic aromatic hydrocarbon (PAH) with the chemical formula C10H8. It is a white, volatile solid that is best known as the main ingredient in traditional mothballs.
Etymology
The term "naphthalene" comes from the Persian word naft, meaning "naphtha" (a broad term encompassing any volatile, flammable liquid hydrocarbon mixture), and the suffix -ene, a standard ending for hydrocarbons.
Chemical Properties
Naphthalene is a crystalline, white, aromatic hydrocarbon, consisting of two fused benzene rings. It is insoluble in water but soluble in common organic solvents. It sublimes easily and has a strong, characteristic smell.
Uses
Naphthalene is primarily used as a moth repellent, but it also has other uses. It is used in the production of phthalic anhydride, and it can also be used in the manufacture of certain dyes, resins, and insecticides.
Health Effects
Exposure to large amounts of naphthalene may damage or destroy red blood cells, a condition known as hemolytic anemia. Long-term exposure to naphthalene vapors can also cause cataracts and retinal damage.
