Methodology:

The titration method, as described in [1], was used. The titrant, from a weighed pipette, was added to the weighed binary mixture of known composition and the mixture was kept in a thermostated bath. To confirm that the end-point was reached the mixture was shaken automatically for at least 15 min and then reexamined. The plot of refractive index against composition was then used to find compositions of equilibrium phases. The refractive indexes were determined at the temperature of 30.0 °C to eliminate an opalescene.

Sample Information:

1. Eastman Kodak Company, commercial grade; dried by refluxing over active lime, twice distilled; $d_{4}^{25}$ = 0.7866, $n_{D}^{25}$ = 1.326 59.
2. Not specified.
3. Eastman Kodak Company, commercial grade; distilled in an atmosphere of purified $\ce{N2}$, collected in dried nitrogen-filled bottles; $d_{4}^{25}$ = 0.8056, $n_{D}^{25}$ = 1.4434.

Measurement Errors:

Ambient temperature: Temp. ±0.05°C.
