Glass Ball as Bullet Solubility System: Hexane with Water

Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Hexane; C6H14; [110-54-3]  NIST Chemistry WebBook for detail

Original Measurements:
   Aquan-Yuen, M.; Mackay, D.; Shiu, W.Y., J. Chem. Eng. Data 1979, 24, 30-4.

Variables:
   Temperature = One temperature: 25 °C

Prepared By:
   M.C. Haulait-Pirson

Experimental Remarks:

   The solubility of hexane in water at 25 °C was reported to be 0.0123 g(1) dm-3. With the assumption of a solutin density of 1.00 g cm-3, the corresponding mass perent is 0.00123 g(1)/100 g sln and the corresponding mole fraction, x1, is 2.57 x 10-6 (compiler).

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Saturated solutions were prepared by adding an excess of (1) in (2) for 24 h, followed by settling in the water-bath for at least 48 hrs. The dissolved (1) was extracted by helium and trapped in liquid nitrogen. (1) was then injected into the GC column. The gas chromatograph was a Hewlett-Packard Model equipped with a flame ionization detector. The technique is described in ref 1.

Source and Purity of Materials:
   (1) Fischer Scientific; pure grade (99 mol%).
   (2) not specified.

Estimated Errors:
   Solubility: ± 0.0004 g(1) dm-3 sln (type of error not specified).
