Method/Apparatus/Procedure:
A mixture of 10 mL (1) and 300 mL (2) was placed in a double-walled bottom-stoppered vessel and vigorously stirred magnetically for 10-12 hr. The phases were allowed to separate; a first sample of the water phase was rejected and next 200 mL of this phase was taken, 20-mL aliquots were introduced into 40-mL hermetic bottles and (1) was allowed to equilibrate with the air, and the (1)-saturated air was analyzed by glc.
Source and Purity of Materials:
- source not specified; CP reagent; purity not specified.
- Distilled.
Heptane with Water
Components:
(1) Heptane,
$\ce{ C7H16 }$;
[142-82-5]
NIST WebBook
(2) Water,
$\ce{ H2O }$;
[7732-18-5]
NIST WebBook
Experimental Values:
The solubility of heptane in water at 25°C was reported to be x1 = 5.0 × 10-7.
The corresponding mass percent calculated by the compiler is 2.8 × 10-4 g(1)/100 g sln.
