phenanthrene

A colorless aromatic crystalline hydrocarbon, C₁₄H₁₀, obtained by fractional distillation of coal-tar oils and used in dyes, drugs, and explosives.

A crystalline hydrocar- bon, , found in coal-tar, and formed when various hydrocarbons are passed through red-hot tubes. Its solutions have a slight blue fluorescence. It melts at 99° C., but sublimes at a lower temperature.

A complex hydrocarbon, C14H10, found in coal tar, and obtained as a white crystalline substance with a bluish fluorescence.

A tricyclic aromatic hydrocarbon obtained from coal tar; used in the manufacture of dyes, pharmaceuticals and explosives; it is isomeric with anthracene.
