Method/Apparatus/Procedure:
   Tritiated water was shaken with iodobenzene in 1:10 volume ratios for 4 hours in flasks placed in a water thermostat bath. The water content was determined by tritium assay of samples taken from the flasks. The count rates were determined using a typical liquid scintillator solution technique.

Source and Purity of Materials:
   (1) Tritiated.
   (2) Source not known, laboratory grade, dried over CaCI₂ and fractionally distilled before use.

Estimated Errors:
   Solubility: ± 5%.
   Temperature: ± 0.5 K (compiler).
