4-Bromophenyl phenyl ether is a brominateddiphenylether and a liquid at common ambient temperatures.Molecular weight=249.10; Boiling point=310.14 ℃;Specific gravity (H2O:1)=1.449 (1.4208 at 20 ℃);Freezing/Melting point=18.72℃; Vapor pressure 50.0015 mmHg at 20℃; Flash point=.110℃. HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 1, Reactivity 0. Poor solubility inwater; solubility=4.8 mg/L at 25℃.
ChEBI: An aromatic ether that is diphenyl ether substituted at position 4 by a bromo group.
Liquid. Freezing point 18°C. Density 1.423 g / cm3. Insoluble or slightly soluble in water.
4-Bromophenoxybenzene oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164].
Very little information on 4-bromophenyl phenyl ether exists. It is prepared by brominatingdiphenyl ether with Br2 at 95-100℃ in carbontetrachloride.[US EPA, 1986] 4-Bromophenyl phenyl ether hasbeen identified in raw water, in drinking water, and in riverwater.
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
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).
Color Code—Green: General storage may be used.Store away from heat, flames, or oxidizing materials; etherstend to peroxidize when exposed to air formingunstable peroxides that may detonate with extreme violence.
The name of this material is not on the DOT listof materials for label and packaging standards. However,based on regulations, it may be classified as anEnvironmentally hazardous substances, liquid, n.o.s. It fallsin Hazard Class 9 and Packing Group III.[20, 21]
