Conditions:
Room Temp: 246 - 269 $\pu{K}$
Compilers:
Methodology:
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 $\pu{\pm 0.05 K}$.
Sample Information:
- Commercial Solvents Corp.; purity 96 mole% with 3.9 mole% of 2-nitropropane; not purified.
- Phillips Petroleum Co.; purity >99 mole%; not purified.
Measurement Errors:
Ambient temperature: to ±0.1 K (synthetic method).
Mass concentration (m/v) (1): Composition: ±0.5 mass% (analytical method).
