Method/Apparatus/Procedure:
   Tritiated water was shaken with 1,2-dichlorobenzene in 1:10 volume ratios for 4 hours in a flask in a water thermostat bath. The water content was determined by tritium assay. 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 CaCl₂ and fractionally distilled before use.

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