 Method/Apparatus/Procedure:
   Equilibration flask: 50-mL glass-stoppered flask. The flask was heated in a hot-water bath until the hydrocarbon was melted, then shaken vigorously while cooling until excess hydrocarbon had recrystallized. The flask was then placed into a water bath thermostatically controlled at 25.00 ± 0.05°C for at least 48 hr, and shaken occasionally during that time. Samples were withdrawn with a 10-ml transfer pipet, diluted appropriately and analyzed using a spectrophotometer in the ultra-violet region of the spectrum.

 Source and Purity of Materials:
   (1) recrystallized from menthanol (source not specified)
   (2) reagent grade, dried at 120°C before weighing (source not specified)
   (3) redistilled. (source not specified)

 Estimated Errors:
   Solubility: ± 2.6%
   Temperature: ± 0.05°C
