t/°CMole Fraction x1Mole Fraction x2
20.00.02840.9716
 Method/Apparatus/Procedure:
   Constant temperature bath, thermometer, and a precision balance.
Excess solute placed in closed glass container and allowed to equilibrate for several hours at constant temperature. Aliquots of saturated solutions were transferred into tared containers and weighed. Solubilities calculated from weight of solid residue that remained after solvent had evaporated.

 Source and Purity of Materials:
   (1) 95 % initial purity, source not given, was recrystallized several times from toluene and ethanol to give a melting temperature of 150.5-150.9 ºC.
   (2) Commercial sample, purity and source not specified, was dehydrated and distilled before use.

 Estimated Errors:

   Temperature: T/K: ± 0.05. x1: ± 3 % (relative error; compiler).
