ABSTRACT
CASRN: 100-74-3; DOT: 1993; molecular formula: C6H13NO; FW: 115.18; RTECS: QE4025000 Physical state, color, and odor: Colorless, flammable liquid with an ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 400 µg/m3 (85 ppbv) and 1.2 mg/m3 (250 ppbv), respectively (Hellman and Small, 1974). Melting point (°C): -65 to -63 (quoted, Verschueren, 1983) Boiling point (°C): 138-139 at 763 mmHg (Weast, 1986) Density (g/cm3): 0.905 at °C (Aldrich, 1990) Diffusivity in water (x 10-5 cm2/sec): 0.81 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 32.5 (open cup, NIOSH, 1997) 27 (Aldrich, 1990) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for substituted morpholines are lacking in the documented literature. However, its high solubility in water suggests its adsorption to soil will be nominal (Lyman et al., 1982). Solubility in organics: Soluble in acetone, alcohol, benzene, and ether (Weast, 1986) Solubility in water: Miscible (Hawley, 1981). Vapor density: 4.71 g/L at 25 °C, 3.98 (air = 1) Vapor pressure (mmHg at 20 °C): 6.1 (quoted, Verschueren, 1983) Environmental fate: Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).
