Room Temp: 298 $\pu{K}$

Methodology:
The points on the binodal curve were determined by the formation of a cloudy mixture on shaking after the addition of a known mass of one component to a mixture of known masses of the other two components. Precision weighing syringes were used as described in [1]. Tie line compositions were determined by the refractive index method reported in [2] and complementary method using the Karl Fischer titrations as reported in [3].
Sample Information:
- Merck, AR grade; refluxed with $\ce{Mg}$ and $\ce{I2}$, distilled; purity $\pu{\gt 99.6 mole%}$ by GLC; $d$ = 0.78151, $n$ = 1.3752.
- BDH; used as received; purity better than 99.6 mole% by GLC; $d$ = 0.86032, $n$ = 1.54946.
- Source not specified.
Measurement Errors:
Ambient temperature: Estimated comp. 0.005 mole fraction on the binodal curve and 0.01 mole fraction for tie lines (estimated by the authors).
Mass concentration (m/v) (1): Not reported.
