Naphthalene volatility

WitrynaNaphthalene is a polycyclic aromatic hydrocarbon that exists at room temperature as a white crystalline solid with an aromatic odor. It is insoluble in water but soluble in methanol, ethanol, benzene, toluene, olive oil, turpentine, chloroform, carbon tetrachloride, ether, hydro-naphthalenes, fixed and volatile oils, and ethylene dichloride. WitrynaNaphthalene (not to be confused with naphtha ), also known as naphthalin, naphthaline, tar camphor, white tar, or albocarbon, is a crystalline, aromatic, white, solid hydrocarbon, best known as the traditional, primary ingredient of mothballs. It is volatile, forming a flammable vapor, and readily sublimes at room temperature.
