Descrizione

Descrizione generale

Diphenyl ether (diphenyl oxide) belongs to the family of aromatic homomonocyclic compounds. It is colorless, exists as crystalline solid or liquid (above 82°F) and has a geranium-like odor. Diphenyl ether is present in alcoholic beverages. It is used as a flavouring ingredient and is found in vanilla, green tea, muscat grapes, potato chips, grilled beef, buckwheat, and lemon balm. It is a starting material in the production of phenoxathiin via the Ferrario reaction.. In similar reactions, diphenyl ether is a significant side product in the high-pressure hydrolysis of chlorobenzene during production of phenol. Also several polybrominated diphenyl ethers (PBDEs) are useful flame retardants.
