Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Toluene; C7H8; [108-88-3]  NIST Chemistry WebBook for detail
Original Measurements:
   Caddock, B.D.; Davies, P.L., J. Inst. Petrol. 1960, 46, 391-6.

 Variables:
   Temperature = One temperature: 20 °C

 Prepared By:
   A. Maczynski

 Experimental Remarks:
   The solubility of water in toluene at 20 °C was reported to be 46 mg(2)/100 g(1).
The corresponding mass percent and mole fraction, x2, calculated by the compiler are 0.046 g(2)/100 g sln and 0.0023.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   A sample of (1) was equilibrated at 20 °C with an air stream containing a known amount of water vapor tagged with HTO. At equilibrium a sample of (1) was taken and its (2) content determined by liquid scintillation counting.
