Method/Apparatus/Procedure:
   The analytical method was used. Compositions of equilibrium liquid phases were determined by gas chromatography. Mixtures were stirred periodically while kept in a water bath at the specified temperature. Equilibrium time was 2 hrs. to 4 hrs. Samples for analysis were withdrawn with the aid of a MSh-10 microsyringe through a rubber stopper.

Source and Purity of Materials:
   (1) Source not specified; pure grade reagent; dried and repeatedly distilled in a packed column of 20 theoretical plates; no impurities detectable by gas chromatography.
   (2) Source not specified; pure grade reagent; dried and repeatedly distilled at vacuum; 99.5 mole % purity.
   (3) Twice distilled.

Estimated Errors:

   Temperature: control to ± 0.02 K.
