 Method/Apparatus/Procedure:
   The solute isopiestic method was used without modification. The apparatus employed consisted of a closed vessel divided into two compartments, one for water and the other for the organic solvent. Equilibrium was attained after a period of  6 to 8 hours. Samples of the solution were analyzed for water with the Beckman KH-3 Aquameter. The Karl Fischer reagent was standardized against crystalline sodium tartarate dihydrate.

 Source and Purity of Materials:
   (1) Distilled.
   (2) Source not given, certified or reagent grade, distilled through a 30-plate Oldershaw column before use.

 Estimated Errors:
   Solubility: See table above.
   Temperature: ± 0.1 K.
