Conditions:
Room Temp: 298 $\pu{K}$
Compiler:
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:
- Merck, AR grade; distilled, dried by the addition of anhydrous potassium carbonate, distilled; purity better than $\pu{99.6 mole%}$ by GLC.
- BDH; used as received; purity better than $\pu{99.6 mole%}$ by GLC.
- 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.
