Method/Apparatus/Procedure:
The mutual solubility data were determined by the method described by Othmer et al. (ref. 1). A 10 cm
3
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).
