   The mutual solubility data were determined by the method described by Othmer et al. (ref. 1). A 10 cm3 dichloromethane sample was added to water from a buret and agitated until the solution became turbid. The appearance of the turbidity indicated the  formation of a second phase. The solubilities were calculated by means of known densities and volumes.

Source and Purity of Materials:
   (1) Probus reagent, further purified by distillation in a heli-packing column.
   (2) Distilled.

Estimated Errors:
   Solubility: Not specified.
   Temperature: ± 0.5 K (compiler).
