Notes:
a
Obtained by synthetic method. All other data obtained by the analytical method.
Method/Apparatus/Procedure:
The synthetic method 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);
