ABSTRACT
CASRN: 111-15-9; DOT: 1172; DOT label: Flammable liquid; molecular formula: C6H12O3; FW: 132.18; RTECS: KK8225000; Merck Index: 13, 3798 Physical state, color, and odor: Colorless liquid with a faint, pleasant odor. Experimentally determined detection and recognition odor threshold concentrations were 300 µg/m3 (60 ppbv) and 700 µg/m3 (130 ppbv), respectively (Hellman and Small, 1974). Nagata and Takeuchi (1990) reported an odor threshold concentration of 49 ppbv. Melting point (°C): -61.7 (NIOSH, 1997) Boiling point (°C): 156 (NIOSH, 1997) Density (g/cm3): 0.975 at 20/20 °C (Windholz et al., 1983) Diffusivity in water (x 10-5 cm2/sec): 0.74 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 54.4 (closed cup), 59.4 (open cup) (Eastman, 1995) Upper explosive limit (%): 51.5 (NIOSH, 1997); 56 (open cup, Windholz et al., 1983) Lower explosive limit (%): 1.7 (NIOSH, 1997) Henry’s law constant (x 10-7 atm⋅m3/mol): 9.07 at 25 °C (approximate - calculated from water solubility and vapor pressure) 33.0 at 30.00 °C (headspace-GC, Hovorka et al., 2002) 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). Octanol/water partition coefficient, log Kow: 0.50 using method of Hansch et al. (1968)
230,000 mg/L at 20 °C (quoted, Verschueren, 1983) Vapor density: 5.40 g/L at 25 °C, 4.56 (air = 1) Vapor pressure (mmHg): 2 at 20 °C (NIOSH, 1997) 1.2 at 20 °C, 3.8 at 30 °C (quoted, Verschueren, 1983) Environmental fate: Biological. Bridié et al. (1979) reported BOD and COD values of 0.74 and 1.76 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d. The ThOD for 2-ethoxyethyl acetate is 1.82 g/g. Chemical/Physical. At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 342 mg/L. The adsorbability of the carbon used was 132 mg/g carbon (Guisti et al., 1974). Exposure limits: NIOSH REL: TWA 0.5 ppm (2.7 mg/m3), IDLH 500 ppm; OSHA PEL: TWA 100 ppm (540 mg/m3); ACGIH TLV: TWA 5 ppm (adopted). Toxicity: Acute oral LD50 for guinea pigs 1,910 mg/kg, rats 2,900 mg/kg, rabbits 1,950 mg/kg (quoted, RTECS, 1985). Uses: Automobile lacquers to reduce evaporation and to impart a high gloss; solvent for nitrocellulose, oils, and resins; varnish removers; wood stains; textiles; leather.
