ABSTRACT
CASRN: 109-89-7; DOT: 1154; DOT label: Flammable liquid; molecular formula: C4H11N; FW: 73.14; RTECS: HZ8750000; Merck Index: 12, 3160 Physical state, color, and odor: Colorless liquid with a fishy, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 60 µg/m3 (20 ppbv) and 180 µg/m3 (60 ppbv), respectively (Hellman and Small, 1974). Melting point (°C): -50 (Windholz et al., 1983) Boiling point (°C): 55.3 (Resa et al., 2000) 55.2 (Aucejo et al., 1983) Density (g/cm3): 0.711 at 18 °C (quoted, Verschueren, 1983) 0.7056 at 20 °C (Weast, 1986) 0.69899 at 25.00 °C (Resa et al., 2000) Diffusivity in water (x 10-5 cm2/sec): 1.11 at 25 °C (quoted, Hayduk and Laudie, 1974) Dissociation constant, pKa: 11.090 at 20 °C (Gordon and Ford, 1972) 10.93 at 25 °C (Dean, 1973) Flash point (°C): -28 (Aldrich, 1990) Lower explosive limit (%): 1.8 (NIOSH, 1997) Upper explosive limit (%): 10.1 (NIOSH, 1997) Henry’s law constant (x 10-5 atm⋅m3/mol): 2.56 at 25 °C (Christie and Crisp, 1967) Ionization potential (eV): 8.01 ± 0.01 (Franklin et al., 1969) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for aliphatic amines are lacking in the documented literature. However, its high solubility in water suggests its adsorption to soil will be nominal (Lyman et al., 1982).
