ABSTRACT
Br CASRN: 101-55-3; molecular formula: C12H9BrO; FW: 249.11 Physical state: Liquid Melting point (°C): 18.7 (Weast, 1986) Boiling point (°C): 310.1 (Weast, 1986) 305 (Aldrich, 1990) Density (g/cm3): 1.4208 at 20 °C (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.63 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): >110 (Aldrich, 1990) Henry’s law constant (x 10-4 atm⋅m3/mol): 1 (Pankow and Rosen, 1988) 2.27 at 25 °C (integrated gas-stripping method, GC, Lau et al., 2006) Soil organic carbon/water partition coefficient, log Koc: 4.94 using method of Karickhoff et al. (1979) Octanol/water partition coefficient, log Kow: 5.15 (quoted, Walton, 1985) Solubility in organics: Soluble in ether (Weast, 1986) and many other solvents including 1,4-dioxane, benzene, and toluene. Vapor density: 10.19 g/L at 25 °C, 8.60 (air = 1) Vapor pressure (mmHg): 1.94 x 10-3 at 25 °C (subcooled liquid, Tittlemier et al., 2002)
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). Toxicity: LC50 (96-h) for bluegill sunfish 5.9 mg/L (Spehar et al., 1982). LC50 (48-h) for Daphnia magna 0.36 mg/L (LeBlanc, 1980). LC50 (24-h) for Daphnia magna 0.46 mg/L (LeBlanc, 1980). Use: Research chemical.
