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.
- doubly distilled; free of trace organics.
Estimated Errors:
Ambient temperature: ±0.5°C
Mass concentration (m/v) (1): ±1.2 mg(1)/kg(2) (from eight determinations)
Components:
- 1-Methylnaphthalene, $\ce{ C11H10 }$; [90-12-0] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of 1-methylnaphthalene in water at 25°C was reported to be 25.8 mg(1)/kg (2) and 1.81 × 10-4 mol(l) L (2).
The corresponding mass percent and mole fraction, x1, calculated by the compiler are 2.58 × 10-3 g(1)/100 g sln and 3.27 × 10-6.
