ABSTRACT

CH3 CASRN: 4516-69-2; molecular formula: C8H16; FW: 112.22 Physical state and color: Colorless liquid Melting point (°C): -14.4 (quoted, Mackay et al., 1982) Boiling point (°C): 104.89 °C (Wilhoit and Zwolinski, 1971) Density (g/cm3): 0.7703 at 20 °C (Weast, 1986) Diffusivity in water (x 10-5 cm2/sec): 0.71 at 20 °C using method of Hayduk and Laudie (1974) Dissociation constant, pKa: >14 (Schwarzenbach et al., 1993) Henry’s law constant (atm⋅m3/mol): 1.56 at 25 °C (Mackay and Shiu, 1981) Soil organic carbon/water partition coefficient, log Koc: Unavailable because experimental methods for estimation of this parameter for alicyclic hydrocarbons are lacking in the documented literature Octanol/water partition coefficient, log Kow: 3.34 (calculated, Wang et al., 1992) Solubility in organics: Miscible with cyclopentane, cyclohexane, methylcyclohexane, dimethylcyclohexane Solubility in water: 3.73 mg/kg at 25 °C (shake flask-GLC, Price, 1976) Vapor density: 4.59 g/L at 25 °C, 3.87 (air = 1) Vapor pressure (mmHg): 39.7 at 25 °C (Wilhoit and Zwolinski, 1971) Environmental fate: Chemical/Physical. 1,1,3-Trimethylcyclopentane will not hydrolyze because it does not contain

Complete combustion in air yields carbon dioxide and water. Uses: Organic synthesis; gasoline component.
