Variables:

Room Temp: 298 $\pu{K}$

Prepared by:

A. Skrzecz

Method/Apparatus/Procedure:

The titration method, Refs. 1, 2, was used. Binary mixtures of known composition were titrated with the third component. The total weight of liquids employed was 13-15g. The refractive indexes of mixtures were used to construct the refractive index/composition curve, which was used further to find compositions of equilibrium phases.

Source and Purity of Materials:

1. Eastman Kodak Company, best grade; dried with active lime, distilled; $d_{4}^{25}$ = 0.7808, $n_{D}^{25}$ = 1.3749.
2. Eastman Kodak Company; distilled, dried with $\ce{Na}$, recrystallized several times; $d_{4}^{25}$ = 0.7746, $n_{D}^{25}$ = 1.4232, FP = 6.1°C.
3. Source not specified.

Estimated Errors:

Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
