Photochemistry of anthracene in water

Photooxidation of Polycyclic Aromatic Hydrocarbons over NaBiO3 under Visible Light Irradiation

“…In photolysis process, ANT was directly excited by light and reacted with singlet oxygen to form 9,10-endoperoxyanthracene, and then rearrangement and further oxidation of the endoperoxide leaded to the formation of anthraquinone. As a result, anthrone was never produced in photolysis process [24,25]. As mentioned above, we can conclude that anthrone, one of the products, was generated from ANT photooxidation over SAMPLE-A.…”

Environmental Carcinogenic Polycyclic Aromatic Hydrocarbons: Photochemistry and Phototoxicity

“…This oxidative process is one of the chief degradation pathways for PAHs in the natural aquatic environment. Photodegradation products of the following PAHs are characterized: naphthalene in vapor (51)(52)(53), phenanthrene in silica-air inter-phase (54,55), anthracene in aqueous and organic solvents (56)(57)(58)(59)(60), pyrene in soil surface or on carbon (61-64), benzo[a]pyrene in aqueous media (65,66), and some heterocyclic compounds in solutions or on solid surfaces. Since then, characterization of photoproducts of some PAH in aqueous or water/organic solvent mixtures are available: naphthalene (53), pyrene (67,68), benz [a]anthracene (57,69,70), methyl substituted BAs (69), 1-hydroxypyrene (71), and 1-aminopyrene (AP).…”

“…Upon light irradiation, both anthracene and BA react with oxygen to form endoperoxides. Rearrangement and further oxidation of the endoperoxides lead to the formation of quinones (58,59,69,72) (Figure 4). Irradiation of 7,12-dimethyl-BA in aqueous solutions leads to the formation of 7,12-endoperoxide and subsequently to 7,12-BA-quinone (70) ( Figure 5).…”

Photoirradiation of Polycyclic Aromatic Hydrocarbons with UVA Light – A Pathway Leading to the Generation of Reactive Oxygen Species, Lipid Peroxidation, and DNA Damage

“…It has been found that upon light irradiation, anthracene, benz[a]anthracene (BA), pyrene, 5-methylbenz[a]anthracene, 7,12-dimethyl-BA (DMBA), and benzo[a]pyrene react with oxygen to form endoperoxides as intermediates and the corresponding quinones as the end products [17,[43][44][45][46][47][48][49][50]. These results indicate that quinones are the stable end photoproducts of PAH light irradiation.…”
