ABSTRACT
CASRN: 110-49-6; DOT: 1189; DOT label: Combustible liquid; molecular formula: C5H10O3; FW: 118.13; RTECS: KL5950000; Merck Index: 12, 6119 Physical state, color, and odor: Colorless liquid with a mild, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were 1.6 mg/m3 (330 ppbv) and 3.1 mg/m3 (640 ppbv), respectively (Hellman and Small, 1974). Melting point (°C): -65 (NIOSH, 1997) -70 (Windholz et al., 1983) Boiling point (°C): 144-145 (Weast, 1986) Density (g/cm3): 1.0090 at 19/19 °C (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.81 at 19 °C using method of Hayduk and Laudie (1974) Flash point (°C): 48.9 (closed cup), 51.7 (open cup) (Eastman, 1995) 54 (Windholz et al., 1983) Lower explosive limit (%): 1.7 (NFPA, 1984) Upper explosive limit (%): 8.2 (NFPA, 1984) Henry’s law constant (x 10-6 atm⋅m3/mol): 3.28 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 cellosolve esters are lacking in the documented literature. However, its miscibility in water suggests its adsorption to soil will be nominal (Lyman et al., 1982). Octanol/water partition coefficient, log Kow: Unavailable because experimental methods for estimation of this parameter for cellosolve esters are lacking in the documented literature
Soluble in alcohol and ether (Weast, 1986) Solubility in water: Miscible (Lyman et al., 1982) Vapor density: 4.83 g/L at 25 °C, 4.08 (air = 1) Vapor pressure (mmHg at 20 °C): 2 (NIOSH, 1997) 7 (quoted, Verschueren, 1983) Environmental fate: Chemical/Physical. Hydrolyzes in water forming methyl cellosolve and acetic acid. At an influent concentration of 1,024 mg/L, treatment with GAC resulted in an effluent concentration of 886 mg/L. The adsorbability of the carbon used was 28 mg/g carbon (Guisti et al., 1974). Exposure limits: NIOSH REL: TWA 0.1 ppm (0.5 mg/m3), IDLH 200 ppm; OSHA PEL: TWA 25 ppm (120 mg/m3); ACGIH TLV: TWA 5 ppm (24 mg/m3). Toxicity: Acute oral LD50 for guinea pigs 1,250 mg/kg, mice 3,390 mg/kg (quoted, RTECS, 1985). Uses: Solvent for cellulose acetate, nitrocellulose, various gums, resins, waxes, oils; textile printing; lacquers; dopes; textile printing; photographic film.
