Description and Uses
Anthracene is one of a group of chemicals called polycyclic aromatic hydrocarbons (PAHs). PAHs are often found together in groups of two ormore. They can exist inmore than 100 different combinations, but the most common are treated as a group of 15. PAHs are found naturally in the environment but they can also be made synthetically. Anthracene can vary in appearance from a colorless to pale yellow crystal-like solid. PAHs are created when products like coal, oil, gas, and garbage are burned but the burning process is not complete. Very little information is available on the individual chemicals within the PAH group; the majority of the information is for the entire PAH group. Anthracene is a solid white to yellow crystal, has a weak aromatic odor, and sinks in water. Its characteristics are boiling point, 3421°C; melting point, 2181°C; molecular weight, 178.22; density/specific gravity, 1.25 at 27 and 41°C; octanol–water coefficient, 4.45. It is soluble in absolute alcohol and organic solvents. Maximum absorption occurs at 218 nm.
Anthracene has been shown to be soluble in a variety of binary and ternary mixtures of cyclohexanone, ethyl acetate, and methanol 1,2.
