Original Measurements
Letcher, T. M.; Siswana, P. M.; van der Watt, P.; Radloff, S.; J. Chem. Thermodyn. 21, 1053 (1989).
Variables:
Room Temp: 298 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
The titration method was used to determine binodal curve. A binary mixture of known composition was titrated with the third component until cloudiness was observed. Tie line compositions were related to the coexisting curve; water was determined by Karl Fischer titration. The methods were described in [1].
Source and Purity of Materials:
- Source not specified; used as received.
- Source not specified; recrystallized three times.
- Source not specified.
Estimated Errors:
Ambient temperature: Comp. <0.005 mole fraction (estimated authors' precision on binodal curve), <0.01 mole fraction (estimated authors' precision of tie lines).
Mass concentration (m/v) (1): Not reported.
