Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C 14 H 8 O 2. Anthracene also reacts with dienophile singlet oxygen in a [4+2]-cycloaddition (DielsAlder reaction): Chemical oxidation occurs readily, giving anthraquinone, C14H8O2 (below), for example using hydrogen peroxide and vanadyl acetylacetonate. In addition different solvents of this sort are: chloroform, benzene, toluene, xylene, ketones, hexane, cyclohexane and carbon tetrachloride. The 1-butanol and 1-octanol are non-polar because of their carbon chains, which can be drawn to the non-polarity of the hexane. An anthracene is a tricyclic aromatic hydrocarbon obtained from If the structure of a molecule is such that the individual bond dipoles do not cancel one another, then the molecule has a net dipole moment. Anthracene is purified by sublimation. The cyclodehydration of O-methyl or o-methyl-substituted diaryl ketones in the so-called Elbs reaction is a classic process for preparing anthracene in the laboratory. As Anthracene is present naturally without any reaction with coal tar then it is neutral in nature. [13], Coal tar, which contains around 1.5% anthracene, remains a major source of this material.

Anthracene is a colourless crystalline aromatic hydrocarbon utilised in the chemical industry that is created by distilling natural crude oils. Use local exhaust ventilation where the chemical is released. Its hydrophobicity could also be expressed by the logarithm of the octanol/water partition coefficient Log P 10. 2. Anthracene is insoluble in water however is fairly soluble in carbon disulfide and somewhat soluble in ethanol, methanol, benzene, chloroform, and other natural solvents. It is now considered aromatic because it obeys Hckels rule: In the case of benzene, we have 3 bonds (6 electrons), so 4n+2=6 . This occurs when two anthracene molecules join together to produce a bigger hydrocarbon structure. ChemSpider ID 8111. Naphthalene and anthracene are non-polar, so soluble in non-polar solvents like benzene. Some of the higher predicted solubility figures for commonplace solvents come with 3.85M for hexane and 9.74M for ethyl acetate. However, both these compounds contain three benzene rings per molecule. Anthracene is fused linearly, whereas phenanthrene is fused at an angle. If it is benzene, then how come the heat of hydrogenation of benzene to cyclohexane is an exothermic process which releases energy, indicating that cyclohexane is more stable. Anthracene is purified by sublimation. The method of preparing the luminescent system, generally, comprises the steps of modifying the surface of a nanostructured material to create isolated regions to act as luminescent centers and to create a charge imbalance on the surface .
