ABSTRACT
CASRN: 556-52-5; DOT: 2810; molecular formula: C3H6O2; FW: 74.08; RTECS: UB4375000; Merck Index: 12, 4499 Physical state, color, and odor: Clear, colorless, and odorless liquid Melting point (°C): -45 (NIOSH, 1997) Boiling point (°C): Decomposes at 166-167 (Weast, 1986) 162 (Hawley, 1981) Density (g/cm3): 1.1143 at 25 °C (Weast, 1986) 1.165 at 0 °C (quoted, Verschueren, 1983) Diffusivity in water (x 10-5 cm2/sec): 0.23 at 25 °C using method of Hayduk and Laudie (1974) Flash point (°C): 72.8 (NIOSH, 1997) 81 (Aldrich, 1990) Ionization potential (eV): 10.43 (Lias and Liebman, 1998) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for epoxy aliphatic alcohols are lacking in the documented literature. However, its high solubility in water and low Kow suggest its adsorption to soil will be nominal (Lyman et al., 1982). Octanol/water partition coefficient, log Kow: -0.95 (shake flask-GLC, Deneer et al., 1988) Solubility in organics: Soluble in acetone, alcohol, benzene, chloroform, and ether (Weast, 1986) Solubility in water: Miscible (NIOSH, 1997) Vapor density: 3.03 g/L at 25 °C, 2.56 (air = 1)
0.9 at 25 °C (quoted, Verschueren, 1983) Environmental fate: Chemical/Physical. May hydrolyze in water forming glycerin (Lyman et al., 1982). Exposure limits: NIOSH REL: TWA 25 ppm (75 mg/m3), IDLH 150 ppm; OSHA PEL: TWA 50 ppm (150 mg/m3); ACGIH TLV: TWA 2 ppm (adopted). Symptoms of exposure: Eye, skin, and lung irritant (Patnaik, 1992) Toxicity: LC50 (14-d) for Poecilia reticulata >319 µg/L (Deneer et al., 1988). Acute oral LD50 for mice 431 mg/kg, rats 420 mg/kg (quoted, RTECS, 1985). Uses: Demulsifier; dye-leveling agent; stabilizer for natural oils and vinyl polymers; organic synthesis.
