40.00.39810.6019
Method/Apparatus/Procedure:
   Constant temperature bath, calorimetric thermometer, and gas chromatograph.
Excess solute and solvent placed in amber glass bottles and allowed to equilibrate for several days at constant temperature. Attainment of equilibrium verified by repetitive measurements. Aliquots of saturated solutions transferred through a coarse filter into tared volumetric flasks, weighed and diluted with cyclohexane.  Concentrations determined chromatographically.

Source and Purity of Materials:
   (1) 99 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, recrystallized 3 times from methanol.
   (2) Spectroanalyzed, Fisher Scientific Chemical Company, Pittsburgh, Pennsylvania, USA, was stored over molecular sieves and distilled shortly before use.

Estimated Errors:

   Temperature: T/K: ± 0.05. x1: ± 1 % (relative error).
