Solubility System: Propylbenzene with Water
Components:

(1) Propylbenzene, C9H12; [103-65-1] NIST WebBook
(2) Water, H2O; [7732-18-5] NIST WebBook

Original Measurements

Stearns, R. S.; Oppenheimer, H.; Simon, E.; Harkins, W. D.; J. Chem. Phys. 1947, 15, 496-507.

Variables:

Ambient temperature: 25 °C

Prepared by:

A. Maczynski, D.G. Shaw

Method/Apparatus/Procedure:

Mixtures of (1) in (2) of known composition were shaken for at least 48 hours. The turbidity was then measured with a photometer. Turbidities of several mixture compositions were plotted and the sharp break point taken as the solubility.

Source and Purity of Materials:
  1. Not specified.
  2. not specified.
Estimated Errors:

Ambient temperature: ±3°C

Experimental Values:
Note: The solubility of propylbenzene in water at 25°C was reported to be 0.012 g(1)/100 g sln.
The corresponding mole fraction, x1, calculated by the compiler is 1.8 × 10-5.
