Method/Apparatus/Procedure:
   The measurements were carried out in the autoclave for vapor-liquid equilibrium determination. The solubility points were obtained by incremental addition of (2) followed by stirring, settling, sampling and analysis. This procedure was continued until addition of water resulted in no pressure increase, indicating three-phase conditions. The samples were analyzed by glc.

Source and Purity of Materials:
   (1) Phillips Petroleum Co.; 99.0% by glc; used as received.
   (2) distilled

Estimated Errors:
   Solubility: ± 0.004 g(2)/100 g sln.
   Temperature: ± 0.5° F.
