 Method/Apparatus/Procedure:
   A mixture of dichloromethane and water was placed in a glass stoppered flask and was shaken intermittently for at least three days in a water bath held at constant temperature. The organic phase was analyzed for water content using the Karl Fischer titrat ion methods. The concentration of dichloromethane in the aqueous phase was analyzed interferometrically.

 Source and Purity of Materials:
   (1) Reagent grade, purified by fractional distillation before use.
   (2) Purified by distillation.

 Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 0.1 K.
