Original Measurements

Verhoeye, L. A. J.; J. Chem. Eng. Data 13, 462 (1968).

Variables:

Room Temp: 298 $\pu{K}$

Method/Apparatus/Procedure:

The binodal curve was determined by titration of heterogeneous mixture with a homogeneous mixture until turbidity ceased. Two-liquid mixture was mixed for 1 h at constant temperature and after separation samples of each phase were analyzed. Liquid-liquid equilibrium data at boiling points (64.30-69.40 °C) at pressure 760 Torr were presented graphically in the paper.

Source and Purity of Materials:
  1. Source not specified; distilled through a glass column (3 cm in diameter, 2 m high, packed in stainless wire) under reflux >10; chosen fractions were used; BP = 80.4°C, $d_{4}^{25}$ = 0.7808, $n_{D}^{25}$ = 1.3749.
  2. Source not specified; distilled through a glass column (3 cm in diameter, 2 m high, packed in stainless wire) under reflux >10; chosen fractions were used; BP = 80.7°C, $d_{4}^{25}$ = 0.7738, $n_{D}^{25}$ = 1.4238.
  3. Twice distilled.
Estimated Errors:

Ambient temperature: Temp. ±1°C; comp. <0.0005 mole fraction (for the binodal curve).
Mass concentration (m/v) (1): Not reported.
