ABSTRACT
CASRN: 100-44-7; DOT: 1738; DOT label: Corrosive material; molecular formula: C7H7Cl; FW: 126.59; RTECS: XS8925000; Merck Index: 12, 1164 Physical state, color, and odor: Colorless to pale yellowish-brown liquid with a pungent, aromatic, irritating odor. Odor threshold concentration is 47 ppbv (Leonardos et al., 1969). Katz and Talbert (1930) reported an experimental detection odor threshold concentration of 210 µg/m3 (41 ppbv). Melting point (°C): -39 (Weast, 1986) Boiling point (°C): 179.3 (Weast, 1986) Density (g/cm3): 1.1002 at 20 °C (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.81 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 67.3 (NIOSH, 1997) Lower explosive limit (%): 1.1 (NIOSH, 1997) Henry’s law constant (x 10-4 atm⋅m3/mol): 3.57 at 20.00 °C (inert gas stripping, Hovorka and Dohnal, 1997) Interfacial tension with water (dyn/cm): 30 at 20 °C (estimated, CHRIS, 1984) Ionization potential (eV): 9.10-9.30 Lias et al., 1998) Soil organic carbon/water partition coefficient, log Koc: 2.28 using method of Chiou et al. (1979) Octanol/water partition coefficient, log Kow: 2.30 (quoted, Leo et al., 1971). It should be noted that benzyl chloride slowly reacts with water yielding benzyl alcohol and HCl. Therefore, this value should be used with caution if it is being used to estimate other physico-chemical and toxicological properties.
