ABSTRACT
H3C CH3 CASRN: 107-08-4; DOT: 2392; DOT label: Combustible liquid; molecular formula: C3H7I; FW: 169.99; RTECS: TZ4100000; Merck Index: 12, 8047 Physical state and color: Clear, colorless liquid with a characteristic sharp, penetrating odor. On exposure to light, 1iodopropane may become pale yellow. Melting point (°C): -101 (Weast, 1986) -98 (Windholz et al., 1983) Boiling point (°C): 102.4 (Weast, 1986) Density (g/cm3): 1.7489 at 20 °C (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.90 at 20 °C using method of Hayduk and Laudie (1974) Flash point (°C): 34 (Acros Organics, 2002) Henry’s law constant (x 10-3 atm⋅m3/mol): 9.09 at 25 °C (Hine and Mookerjee, 1975) Ionization potential (eV): 9.26 ± 0.01 (Franklin et al., 1969) Soil organic carbon/water partition coefficient, log Koc: 2.16 using method of Chiou et al. (1979) Octanol/water partition coefficient, log Kow: 2.54 (shake flask, Abraham et al., 1994) Solubility in organics: Soluble in benzene and chloroform (Weast, 1986). Miscible with alcohol and ether (Windholz et al., 1983). Solubility in water: 0.1065 wt % at 23.5 °C (elution chromatography, Schwarz, 1980) 4,040 mg/kg at 30 °C (shake flask-interferometer, Gross and Saylor, 1931) 5.1 mM at 20 °C (shake flask-turbidimetric, Fühner, 1924) 1.17 x 10-4 at 25 °C (mole fraction, inert gas stripping-GC, Li et al., 1993) 1,070 mg/kg at 25 °C, 1,030 mg/kg at 30 °C (Rex, 1906)
6.95 g/L at 25 °C, 5.87 (air = 1) Vapor pressure (mmHg): 43.1 at 25 °C (Abraham, 1984) 35.1 at 20 °C, 54.8 at 30 °C (Rex, 1906) Environmental fate: Biological. A strain of Acinetobacter sp. isolated from activated sludge degraded 1-iodopropane to 1-propanol and iodide ions (Janssen et al., 1987). Chemical/Physical. Slowly hydrolyzes in water forming 1-propanol and hydroiodic acid. Toxicity: LD50 (inhalation) for rats 73,000 mg/m3/30-min (quoted, RTECS, 1985). Uses: Organic synthesis.
