一般描述
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.

The conversion of lignin, the most recalcitrant of the biopolymers, is necessary for a carbon-efficient utilization of lignocellulosic materials. In this context, hydrogenolysis of lignin is a process receiving increasing attention. In this report, the solvent effects on the hydrogenolysis

Two versatile and fast methods to identify and quantify brominated flame retardants (BrFRs) in styrenic polymers were developed. Gas chromatography/mass spectrometry (GC/MS) as well as gas chromatography with electron-capture detection (GC/ECD), both following ultrasonic-supported dissolution and precipitation (USDP), were applied.
