Notes:
   a  Reported.
   b  Calculated by F. W. Getzen.

Method/Apparatus/Procedure:
   The saturation process was done in sealed Erlenmeyer flasks. The time used for the equilibration was 20 hours. Measured volumes of the saturated solution were then extracted using measured volumes of hexane to remove the aromatic compound from the aqueous layer. The solute concentration was measured spectrophotometrically (1).

Source and Purity of Materials:
   (1) Commercial product (Eastman Kodak Co.), recrystallized twice from ethanol, reporting melting point 360-361 K.
   (2) Source and purity not specified.

Estimated Errors:
   Solubility: >10% (compiler).
   Temperature: ± 0.2 K.
