Glass Ball as Bullet Solubility System: Cumene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Cumene; C9H12; [98-82-8]  NIST Chemistry WebBook for detail
Original Measurements:
   McAuliffe, C., J. Phys. Chem. 1966, 70, 1267-75.

 Variables:
   Temperature = 25 °C

 Prepared By:
   A. Maczynski, Z. Maczynska, and A. Szafranski

 Experimental Remarks:
   The solubility of cumene in water at 25°C was reported to be 50 g(1)/106 g(2).

The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0050 g(1)/100 g sln and 7.5 × 10–6.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   In 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. The bottle was set aside for 2 days to allow droplets of undissolved (1) to separate. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromatographed in conjuction with a flame-ionization detector.

 Source and Purity of Materials:
   (1) Phillips Petroleum or Columbia Chemical; used as received.
   (2) distilled.

 Estimated Errors:
   Solubility: 5 g(1)/106 g(2) (standard deviation of mean)
   Temperature: ± 1.5°C
