Method/Apparatus/Procedure:
The synthetic method with glass ampoules, described in [1], was used to visually determine the phase transition (mass of components in the vapor phase was neglected). Temperature was measured with a mercury thermometer. Compositions of coexisting phases in equilibrium (two liquids and vapor) were determined in a static apparatus. The liquid phases were analyzed by glc. (The pressure was reported during the measurements at temperatures higher than 353.2 K).
Source and Purity of Materials:
- Source not specified.

Estimated Errors:
Ambient temperature: Temp. ±0.2°C (saturation curve) and ±0.5°C (phase equilibrium).
Mass concentration (m/v) (1): Not reported.
