Refined Naphthalene is obtained by further processing crude naphthalene. It is a white or light yellow, flaky or powdery crystal, is easily volatile, and has a special aromatic smell. Refined naphthalene is highly sublime and does not dissolve in water but can dissolve in benzene, alcohol, ethers, chloroform, carbon disulfide, etc.
Refined Naphthalene is the most abundant single component of coal tar. Although the composition of coal tar varies with the coal from which it is produced, typical coal tar is about 10% naphthalene by weight. In industrial practice, distillation of coal tar yields an oil containing about 50% naphthalene, along with twelve other aromatic compounds. This oil, after being washed with aqueous sodium hydroxide to remove acidic components (chiefly various phenols), and with sulfuric acid to remove basic components, undergoes fractional distillation to isolate naphthalene.
