Original Measurements:
   Heric, E.L.; Posey, C.D., J. Chem. Eng. Data 1964, 9, 35-43.

Variables:
   Temperature = 298 K

t/°CMole Fraction x1Mole Fraction x2
25.00.29260.7074
Method/Apparatus/Procedure:
   Constant temperature bath, thermometer, and a precision refractometer.
Excess solute and solvent placed in glass bottles and allowed to equilibrate with gentle agitation for several days at constant temperature. Refractive indices of saturated solutions were measured and solubilities obtained using a calibration curve. Attainment of equilibrium verified by making repetitive  measurements after several additional days.

Source and Purity of Materials:
   (1) Eastman Chemical Company, Rochester, New York, USA, was used as received.
   (2) ACS Grade, Matheson, Coleman and Bell, USA, was dried over calcium hydride and distilled to a final purity of 99.8 %.

Estimated Errors:

   Temperature: T/K: ± 0.01. x1: precision ± 0.0005.
