Variables:
Temperature: 25 °C

Method/Apparatus/Procedure:
A mixture of (1) and (2) was equilibrated for at least 12 hrs in a 200 mL Teflon stoppered vessel with gentle shaking. The solution was allowed to settle for 6 hrs and the aqueous phase was tested (Tyndall effect). Both phases were analyzed by the gas chromatographic technique of internal standardization. The (1) in the aqueous phase was extracted into 5 mL of heptane and the extract analysed by GLC. The instrument was a Hewlett-Packard model equiped with a flame ionization detector.
Source and Purity of Materials:
- Phillips Petroleum Co.; research grade; purity 99%+; used without further purification.
- doubly distilled.
Hexane with Water
Components:
(1) Hexane,
$\ce{ C6H14 }$;
[110-54-3]
NIST WebBook
(2) Water,
$\ce{ H2O }$;
[7732-18-5]
NIST WebBook
Experimental Values:
The solubility of hexane in water at 25°C was reported to be 12.3 mg(1)dm -3 sln corresponding to a mole fraction, x1, of 2.5 × 10-6.
The corresponding mass percent calculated by the compiler is 0.00123 g(1)/100 g sln.
The compiler's calculation assumes a solution density of 1.00 g/mL.
