Methodology:
In a 250 mL glass bottle, 10-20 mL of (1) was vigorously shaken for 1 hr or magnetically stirred for one day, with 200 mL of [2] at 25 °C. In the case of shaking, the solution was allowed to stand for two days to permit separation of small (1) droplets. Absence of emulsion was checked microscopically. A 50 µL sample of the (1) saturated water was withdrawn with a Hamilton Syringe and injected into the fractionator of the gas chromatograph. A hydrogen-flame ionization detector was used. Many details are given in the paper.

System Components:
- Cycloheptane, $\ce{ C7H14 }$; [291-64-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of cycloheptane in water at 25 °C was reported to be 30 mg (1)/kg sln (0.0030 g(1)/100 g sln).
The corresponding mole fraction, x1, calculated by the compiler, is 5.5 × 10-6.
The same value is also reported in [1].
