25.00.02920.9708
35.00.04890.9511
45.00.07220.9278
Method/Apparatus/Procedure:
   Constant temperature bath, a precision thermometer and uv/visible spectrometer.
Mixtures of known concentrations sealed in glass ampoules and pre-equilibrated for four days at an elevated temperature. Saturated solutions were then transferred to a special solubility flask and equilibrated for three days at desired temperature. Aliquots removed, diluted ten-fold with solvent and concentrations determined  spectrophotometrically at 270 nm.

Source and Purity of Materials:
   (1) White Label, Eastman Kodak Company, Rochester, New York, USA, was recrystallized five times from ethanol to give a melting point of 101 ºC.
   (2) Purity not specified, Minnesota Mining & Manufacturing Company, USA, was distilled shortly before use.

Estimated Errors:

   Temperature: T/K: precision ± 0.02. x1: ± 2 % (relative error; compiler).
