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:
- Commercial Solvents Corp.; purity 96 mole% with 3.9 mole% of 2-nitropropane; not purified.
- Phillips Petroleum Co.; purity > 99mole%; not purified.
Estimated Errors:
Ambient temperature: to ±0.1 K (synthetic method).
Mass concentration (m/v) (1): Composition: ±0.5 mass% (analytical method).
