A white volatile solid, C10H8 (see formula); r.d. 1.025; m.p. 80.55°C; b.p. 218°C. Naphthalene is an aromatic hydrocarbon with an odour of mothballs and is obtained from crude oil. It is a raw material for making certain synthetic resins.
Naphthalene
A white crystalline solid with a melting point of 80.5ºC and boiling point of 218ºC, once used as mothballs and widely used as the starting material for plasticers, lubricants, resins, and dyes. It was once produced from coal tar as a by-product of coke production for the steel industry and is now produced as a by-product from petroleum refining as a more pure product. Naphthalene is produced by the process of hydrodealkylation from catalytic reformer bottoms or from recycled materials from cracking operations in the presence of hydrogen using chromium and aluminium oxide catalysts at high temperature.
