Variables:
Ambient temperature: 25 °C

Method/Apparatus/Procedure:
A mixture of 500 mL (2) and 0.001 mol (1) was equilibrated in an Erlenmeyer flask for 12 h (agitation) + 24 h (stationary). The saturated solution, 100 mL, was extracted with hexane, concentrated by evaporation under nitrogen and analyzed by glc. A 5700 A Hewlett-Packard instrument equipped with dual compensating columns and flame ionization detectors was employed.
Source and Purity of Materials:
- source not specified; analytical grade; used as received; no impurities by glc.
- double distilled; free of trace organics.
Estimated Errors:
Ambient temperature: ±0.5°C
Mass concentration (m/v) (1): ±0.4 mg(1)/kg(2) (from eight determinations)
Experimental Values:
Note: The solubility of naphthalene in water at 25°C was reported to be 31.3 mg(1)/kg(2) and 2.43 × 10-4 mol(1) dm-3(2).The corresponding mass percent and mole fraction, x1, calculated by the compiler are 3.13 × 10-3 g(1)/100 g sln and 4.40 × 10-6.
