Glass Ball as Bullet Solubility System: Cyclohexane with Water

Components:
   (1) Cyclohexane; C6H12; [110-82-7]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail

Original Measurements:
   Mackay, D.; Shiu, W.Y.; Wolkoff, A.W., "Water Quality Parameters" Symp. 1973, ASTM Spec. Tech. Publ. 1975, 573, 251-8.

Variables:
   Temperature = Not Specified

Prepared By:
   M.C. Haulait-Pirson

Experimental Remarks:

   The authors reported three different values for the solubility of cyclohexane in water: 55.8, 50.2, and 61.7 mg(1)dm-3 sln. Using the mean value and assuming a solution density of 1.00 g mL-1, the corresponding mass percent, calculated by the compiler, is 0.0056 g (1)/100 g sln and the corresponding mole fraction, x1, is 1.2 x 10-5.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   (1) is partially patitioned into the vapor phase by equilibration of the aqueous sample with helium in a gas syringe, the vapor then being transferred to a gas sampling valve and then to the column of a gas chromatograph equipped with a flame ionization detector. By injecting gas samples from repeated equilibrations it is possible to calculate the amount of (1) in the original sample.
