Conditions:
Room Temp: 298 $\pu{K}$
Compiler:
Methodology:
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 coexistence curve; water was determined by the Karl Fischer titration. The methods were described in [1].
Sample Information:
- Source not specified; used as received.
- Source not specified; recrystallized three times.
- Source not specified.
Measurement 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.
