ABSTRACT
CASRN: 111-76-2; DOT: 2369; DOT label: Poison and combustible liquid; molecular formula: C6H14O2; FW: 118.18; RTECS: KJ8575000; Merck Index: 12, 1594 Physical state, color, and odor: Clear, colorless, oily liquid with a mild, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were 500 µg/m3 (100 ppbv) and 1.7 mg/m3 (350 ppbv), respectively (Hellman and Small, 1974). An odor threshold concentration of 580 ppbv was reported by Nagata and Takeuchi (1990). Melting point (°C): -73.62 (Atake et al., 2000) Boiling point (°C): 171 (Weast, 1986) Density (g/cm3): 0.9015 at 20 °C (Weast, 1986) 0.89623 at 25.00 °C (Chandrasekhar et al., 2000) 0.89231 at 30.00 °C, 0.88386 at 40.00 °C (Venkatesulu et al., 1997) Diffusivity in water (x 10-5 cm2/sec): 0.75 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 61 (Acros Organics, 2002) Lower explosive limit (%): 1.1 at 93 °C (NIOSH, 1997) Upper explosive limit (%): 12.7 at 93 °C (NIOSH, 1997) Henry’s law constant (x 10-6 atm⋅m3/mol): 2.36 (approximate - calculated from water solubility and vapor pressure) Ionization potential (eV): 10.00 (NIOSH, 1997) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for cellosolves are lacking in the documented literature
ow 0.76 at 25 °C (shake flask-GLC, Funasaki et al., 1984) 0.83 at 28 °C (shake flask-refractive index, Korenman and Dobromyslova, 1975) Solubility in organics: Soluble in alcohol, ether (Weast, 1986), and mineral oil (Windholz et al., 1983) Solubility in water: Miscible (Price et al., 1974) Vapor density: 4.83 g/L at 25 °C, 4.08 (air = 1) Vapor pressure (mmHg): 1.9 at 20.00 °C, 2.2 at 30.00 °C, 2.9 at 40.00 °C, 3.4 at 50.00 °C, 4.5 at 60.00 °C, 7.8 at 70.00 °C (static method, Polishchuk et al., 1988) Environmental fate: Biological. Bridié et al. (1979) reported BOD and COD values of 0.71 and 2.20 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. When a sewage seed was used in a separate screening test, a BOD value of 0.20 g/g was obtained. The ThOD for 2-butoxyethanol is 2.31 g/g. Chemical/Physical. At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 441 mg/L. The adsorbability of the carbon used was 112 mg/g carbon (Guisti et al., 1974). Exposure limits: NIOSH REL: TWA 5 ppm (24 g/m3), IDLH 700 ppm; OSHA PEL: TWA 50 ppm (240 mg/m3); ACGIH TLV: TWA 20 ppm (adopted). Symptoms of exposure: An 8-h exposure to 200 ppm may cause nausea, vomiting, and headache (Patnaik, 1992). Toxicity: LC50 (96-h) for brown shrimp 775 mg/L (Blackmann, 1974). LC50 (48-h) for brown shrimp 800 mg/L (Blackmann, 1974). LC50 (24-h static bioassay) for bluegill sunfish at 23 °C is 983 mg/L (quoted, Verschueren, 1983). LC50 (4-h inhalation) values for Fischer-344 rats were 486 and 450 ppm for males and females, respectively (Dodd et al., 1983). LC50 (1-h inhalation) for guinea pigs >633 mg/L (Gingell et al., 1998). Acute oral LD50 for rats is 450 mg/kg (Patnaik, 1992), guinea pigs 1,400 mg/kg (Gingell et al., 1998). Uses: Dry cleaning; solvent for nitrocellulose, cellulose acetate, resins, oil, grease, albumin; perfume fixative; coating compositions for paper, cloth, leather; lacquers.
