Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
Original Measurements:
   Andrews, L.J.; Keefer, R.M., J. Am. Chem. Soc. 1949, 71, 3644-77.

 Variables:
   Temperature = One temperature: 25 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of benzene in water at 25 °C was reported to be 0.174 g(1)/100 g sln.

The corresponding mole fraction, x1, calculated by the compilers is 4.02 x 10-4.

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(2) was rotated for twenty hours in a constant temperature bath at 25°C. A sample (5-20 mL) of the aqueous phase was withdrawn and extracted with a measured volume of hexane (10-50 mL) by shaking in a glass-stoppered Erlenmeyer flask.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

 Source and Purity of Materials:
   (1) Eastman Kodak Co. Best grade; washed successively with concentrated sulfuric acid, water, and dilute sodium hyroxide; dried, and distilled b.p. 80°C.
   (2) not specified.
