 Method/Apparatus/Procedure:
   Tritiated water was equilibrated with 20 ml 1,2-dichlorobenzene by stirring in a flask in a constant temperature water bath for two hours. The concentration of the tritiated water in the organic phase was determined by isotopic dilution. The tritium activities in the tritiated water samples were determined by the acetylene method (1,2). At least four independent experiments were done. The article was based upon work reported in a Ph.D. dissertation (2).

 Source and Purity of Materials:
   (1) Tracerlab Inc., tritiated water, used as received.
   (2) Source not specified, chemical grade, redistilled before use.

 Estimated Errors:
   Solubility: ±1.5%.
   Temperature: ±0.02 K.
