Conditions:

Room Temp: 298 $\pu{K}$

Compiler:

A. Skrzecz

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 by the refractive index method reported in [2] and a complementary method using the Karl Fischer titrations as reported in [3].

Sample Information:
  1. Merck, AR grade; distilled, dried by refluxing with $\ce{Mg}$ and $\ce{I2}$; purity better than 99.6 mole% by GLC; $d$ = 0.78151, $n$ = 1.3752.
  2. BDH; used as received; purity better than 99.6 mole% by GLC; $d$ = 0.87588, $n$ = 1.5029.
  3. 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.
