 Method/Apparatus/Procedure:
   Between 25 and 100 ml of chlorobenzene and 1 to 2 ml D2O were introduced into a flask and shaken for about 90 min. The water bath temperature was maintained within ±0.05°C. Then, a sample was taken and the dissolved D2O content was determined by a modified Karl Fischer titration as described in (1). The original report was unavailable, but the method and the results have been described in sufficient detail in (1). The solubility of H2O in chlorobenzene was also determined and found to be 0.00250 ± 0.00003 mol H2O/ 100 g solution from three separate experiments.

 Source and Purity of Materials:
   (1) Chlorobenzene was carefully purified and dried before use. Source and method not given.
   (2) Source not specified.

 Estimated Errors:
   Solubility: av. dev. ±1 x 10-5 mol D2O/ 100 g solution
   Temperature: ±0.5 K.
