Glass Ball as Bullet Solubility System: Methylcyclopentane with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Methylcyclopentane; C6H12; [96-37-7]  NIST Chemistry WebBook for detail
Original Measurements:
   McAuliffe, C., J. Phys. Chem. 1966, 70, 1267-75.

 Variables:
   Temperature = One temperature: 25 °C

 Prepared By:
   M.C. Haulait-Pirson

 Experimental Remarks:
   The solubility of methylcyclopentane in water at 25 °C was reported to be 42 mg (1)/kg sln.

The corresponding mole fraction, x1, calculated by the compiler, is 9.0 x 10-6.
The same value is also reported in refs 1 and 2.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   n a 250-mL bottle, 10-20 mL of (1) was vigorously shaken for 1 hr, or magnetically stirred for 1 day, with 200 mL of (2) at 25 °C. In the case of shaking, the solution was allowed to stand for 2 days to permit separation of small (1) droplets. Absence of emulsion was checked microscopically. A 50 muL sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromatographed in conjunction with a flame-ionization detector.

 Source and Purity of Materials:
   (1) Phillips Petroleum Co.; 99+% purity; used as received.
   (2) distilled.

 Estimated Errors:
   Solubility: 1.6 mg (1)/kg sln (standard deviation from mean)
   Temperature: ± 1.5 K
