 Notes:
   a  Obtained by synthetic method. All other data obtained by the analytical method.

 Method/Apparatus/Procedure:
   The synthetic and analytical methods were used as described in Vold and Vold.1 The analytical method consisted of withdrawing a sample from each of the coexisting phases from an equilibrium cell in a constant temperature bath, and analyzing the samples by gas chromatographic techniques. The temperature of the bath was controlled to ±0.05 K.

 Source and Purity of Materials:
   (1) Commercial Solvents Corp.; purity 96 mole % with 3.9 mole % of 2-nitropropane; not purified.
   (2) Phillips Petroleum Co.; purity >99 mole %; not purified.

 Estimated Errors:
   Solubility: Composition: ±0.5 mass % (analytical method).
   Temperature: to ±0.1 K (synthetic method);
