25.00.003000.9970
35.00.004610.9954
 Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer.
Mixtures of known concentrations placed in special solubility flask and equilibrated in a constant temperature bath for 48 hours. The entire saturated solution was withdrawn by suction. Solubility based upon weight of undissolved solid, which remained in the solubility flask after solution was removed.

 Source and Purity of Materials:
   (1) Purity and source not given, was recrystallized two times from ethanol.
   (2) Purity and specifies isomer not specified by authors and distilled shortly before use.

 Estimated Errors:

   Temperature: T/K: precision ± 0.5 (compiler). x1: ± 5 % (relative error, compiler).
