ABSTRACT
CASRN: 621-64-7; molecular formula: C6H14N2O; FW: 130.19; RTECS: JL9700000 Physical state and color: Yellow to gold colored liquid Boiling point (°C): 205.9 (Dean, 1973) Density (g/cm3): 0.9160 at 20 °C (IARC, 1978) Diffusivity in water (x 10-5 cm2/sec): 0.72 at 20 °C using method of Hayduk and Laudie (1974) Soil organic carbon/water partition coefficient, log Koc: 1.01 (estimated, Montgomery, 1989) Octanol/water partition coefficient, log Kow: 1.31 (calculated, U.S. EPA, 1980a) Solubility in organics: Very soluble in ethanol and ether (quoted, Keith and Walters, 1992) Solubility in water: 9,900 mg/L at 25 °C (Mirvish et al., 1976) Environmental fate: Chemical/Physical. N-Nitroso-n-propylamine will not hydrolyze because it does not contain a hydrolyzable functional group (Kollig, 1993). At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities were 24, 13, 7.4, and 4.0 mg/g, respectively (Dobbs and Cohen, 1980). Toxicity: LC50 (contact) for earthworm (Eisenia fetida) 11.0 µg/cm2 (Neuhauser et al., 1985). Acute oral LD50 for rats 480 mg/kg (quoted, RTECS, 1985). Use: Research chemical.
