Glass Ball as Bullet Solubility System: (E)-Stilbene with Water

   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) (E)-Stilbene; C14H12; [103-30-3]  NIST Chemistry WebBook for detail

Original Measurements:
   Andrews, L.J.; Keefer, R.M., J. Am. Chem. Soc. 1950, 72, 5034-7.

   Temperature = 25 °C

Prepared By:
   A. Maczynski and Z. Maczynska

Experimental Remarks:

   The solubility of (E)-stilbene in water at 25°C was reported to be 2.9 × 10–5 g(1)/100 g sln.

The corresponding mole fraction, x1, calculated by the compilers is 2 × 10–8.

Experimental Data:   (Notes on the Nomenclature)
   A mixture of (1) and (2) was rotated for twenty hours in a constant temperature bath at 25 °C. A sample (5-20 mL) of the aqueous phase was withdrawn and extracted with a measured volume of hexane (10-50 mL) by shaking in a glass-stoppered Erlenmeyer flask. Next, the absorbance of the hexane phase was measured against a hexane blank on the Beckman spectrophotometer.
