Allgemeine Beschreibung
A clear colorless to dark brownish colored liquid with an aromatic odor. Less volatile fraction separated from coal tar by distillation. Contains naphthalene, acenaphthene, methylnaphthalenes, fluorene, phenol, cresols, pyridine, picolines, among other substances. Flash point greater than 100 °F. Toxic by inhalation and skin absorption. Less dense than water and insoluble in water. Vapors heavier than air. |

Air & Water Reaktionen
Highly flammable. Insoluble in water. |

Reaktivität anzeigen
Saturated aliphatic hydrocarbons, which are contained in NAPHTHA, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water. May be ignited by strong oxidizers. Incompatible with strong oxidizers . |
|
Health Hazard
Primarily a narcotic, causing unconsciousness in high concentrations. The symptoms of acute benzene poisoning are not likely, since the compound has components other than benzene. |
