Method/Apparatus/Procedure:
   An excess of 1,4-dichlorobenzene, 20 g, in water was shaken gently for one week in a water bath at constant temperature. Replicate samples were filtered through a glass-wool plug. Then, the aqueous solution was extracted with cyclohexane which was then analyzed spectrophotometrically for organic solute using a Cary 14 spectrometer. The article was based upon a Ph.D. dissertation (1).

Source and Purity of Materials:
   (1) Recrystallized three times and vacuum-sublimed twice of Matheson, Coleman, and Bell reagent.
   (2) Distilled and deionized.

Estimated Errors:
   Solubility: ±3%.
   Temperature: ±0.5 K.
