   ^b  Reported.
   ^c  Calculated by compiler.

Method/Apparatus/Procedure:
   Equilibrium experiments were carried out in a constant temperature water bath using a stirrer. An equilibration period of at least 5 days was allowed. The total water content in the organic phase was determined by a Karl Fischer titration. Each reported water solubility was obtained as an average of at least two independent determinations.

Source and Purity of Materials:
   (1) Distilled.
   (2)Reagent grade, washed with conc. H₂SO₄ and with 1 M NaHCO₃ and then fractionally distilled over silica gel.

Estimated Errors:
   Solubility: ±4%.
   Temperature: ±0.1 K.
