Method/Apparatus/Procedure:
   Both elution chromatography and UV absorption methods were used to determine the aqueous solubilities. The agreement was within an experimental error of 4% between the two methods. The average deviations were determined from several measurements made on different samples. The analytical procedures for determining organic liquid solubilities in water based upon liquid phase elution chromatography has been described in (1).

Source and Purity of Materials:
   (1) Commercial, 98 wt %.
   (2) Distilled.

Estimated Errors:
   Solubility: ± 4%.
   Temperature: ±0.5 K.
