4-Bromophenoxybenzene Usage And Synthesis

Chemical Properties	light yellow liquid
Definition	ChEBI: An aromatic ether that is diphenyl ether substituted at position 4 by a bromo group.
General Description	Liquid. Freezing point 18°C. Density 1.423 g / cm3. Insoluble or slightly soluble in water.
Air & Water Reactions	Insoluble in water.
Reactivity Profile	4-Bromophenoxybenzene oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164].
Fire Hazard	Combustible.
Environmental fate	Biological. Using settled domestic wastewater inoculum, 4-bromophenyl phenyl ether (5 and 10 mg/L) did not degrade after 28 d of incubation at 25 °C (Tabak et al., 1981). Chemical/Physical. At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities were 303, 112, 41, and 15 mg/g, respectively (Dobbs and Cohen, 1980).
