(5) With picric acid (1)HO·C6H2 (NO2)3 (2,4,6) to form red crystalline anthracene picrate, melting point 138 °C. Dibenzo[a,h]anthracene is a crystalline, carcinogenic aromatic hydrocarbon consisting of five fused benzene rings, produced by the incomplete combustion of organic matter. Dibenzo(a,h)anthracene is primarily found in gasoline exhaust, tobacco smoke, coal tar, soot and certain food products, especially smoked and barbecued foods. Benz[a]anthracene undergoes meso-anthracenic methylation by S-adenosyl-L-methionine (SAM), in the presence of a rat liver cytosol preparation, in vitro, to form 7,12-dimethylbenz[a]anthracene and presumably the moderately active carcinogens 7-methylbenz[a]anthracene and 12-methylbenz[a]anthracene. The major differences between anthracene and phenanthrene lie in the melting point and the properties directly related to solubility (Table 13.2). Phenanthrene is purified as brown to white monoclinic crystals, and also has the characteristic faint aromatic smell.

If The Melting Point Of Your Product Is Below 232-235°C, What Will Be The Possible Reasons?
The melting point of the recrystallized product was 261 - 263°C.
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation.

Anthracene's emission spectrum peaks at between 400 nm and 440 nm. It is also used in wood preservatives, insecticides, and coating materials.
Explain. 2019-08-15 · The key difference between anthracene and phenanthrene is that anthracene is less stable compared to phenanthrene. Anthracene and phenanthrene are structural isomers. They have the same chemical formula, but the structure of the molecule differs from each other. However, both these compounds contain three benzene rings per molecule.

molecular packing alone that determines melting point; anthracene melts around 490 K and phenanthrene around 373 K, although both compounds adopt a herringbone structure. Likewise, chrysene and triphenylene, with the same molecular mass (228.29 g/mol) and herringbone packing have substantially different melting points.
