ABSTRACT
CH3 CASRN: 626-38-0; DOT: 1104; DOT label: Flammable liquid; molecular formula: C7H14O2; FW: 130.19; RTECS: AJ2100000 Physical state, color, and odor: Clear, colorless liquid with a fruity odor. Odor threshold concentration is 2.0 ppb (quoted, Amoore and Hautala, 1983). Melting point (°C): -78.4 (NIOSH, 1994) Boiling point (°C): 134 (Weast, 1986) Density (g/cm3): 0.862-0.866 at 20/20 °C (Hawley, 1981) Diffusivity in water (x 10-5 cm2/sec): 0.69 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 31.7 (NIOSH, 1994) Lower explosive limit (%): 1 (NIOSH, 1994) Upper explosive limit (%): 7.5 (NIOSH, 1994) Henry’s law constant (x 10-4 atm⋅m3/mol): 7.7 at 25 °C (approximate - calculated from water solubility and vapor pressure) Interfacial tension with water (dyn/cm): 44.1 at 20 °C (estimated, CHRIS, 1984) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for aliphatic esters are lacking in the documented literature Octanol/water partition coefficient, log Kow: 5.26 using method of Hansch et al. (1968) Solubility in organics: Soluble in alcohol, ether (Weast, 1986), and many other organic solvents including esters and glycols.
