t/°CMole Fraction x1Mole Fraction x2
25.00.11680.8832
 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 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) Spectroquality, Matheson, Coleman and Bell, USA, was dried over phosphorous pentoxide and distilled to a final purity of 99.99 %.

 Estimated Errors:

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