 Method/Apparatus/Procedure:
   A mixture of 50 ml 1,2-dichlorobenzene and 6 ml water in a botte was submerged in a water thermostat bath for 2 days. The concentration of the water in the organic phase was determined by a conventional Karl Fischer dead stop back titration. Determinations were done in triplicate. A detailed description of the complete experimental procedure has been included in a Ph.D. dissertation (1).

 Source and Purity of Materials:
   (1) Distilled and deionized.
   (2) Fisher - B255, washed with cc. H2SO4 and K2SO3 solution and distilled water. Dried over silica gel and fractionally distilled, purity 99.8%.

 Estimated Errors:
   Solubility: ±1%.
   Temperature: ±0.1 K.
