Method/Apparatus/Procedure:
Saturated solutions of (1) in (2) were prepared in two ways. First, 200 microliters of (1) was injected into 20 mL of (2) and thermostatted at 25 °C. Second, the mixture of (1) and (2) as above was thermostatted at 70 °C and then cooled to 25 °C. The time required to obtain equilibrium was three weeks. The solubility of (1) in (2) was measured by glc. A Perkin-Elmer model F-11 gas chromatograph equipped with a 100-150 mesh Porasil column (70 °C) and a flame ionization detector was used. Saturated solutions of heptane in (2) were used as standard solutions.

Methylcyclohexane with Water
Components:
(2) Water,
$\ce{ H2O }$;
[7732-18-5]
NIST WebBook
(1) Methylcyclohexane,
$\ce{ C7H14 }$;
[108-87-2]

Experimental Values:
The solubility of methylcyclohexane in water at 25°C was reported to be 16.0 mg(1)/kg(2).
The corresponding mass percent and mole fraction, x1, calculated by compiler are 0.0016 g(1)/100 g sln and 2.93 × 10-6.
Editor's Note: Based on the reults for this and other hydrocarbon-water systems, uncertainty exists about whether the datum compiled here is independent of that of Price for the same system (see previous page).
