Room Temp: 273 - 298 $\pu{K}$

Method/Apparatus/Procedure:

A titration method similar to that in [1] was used. A flask of 100 mL capacity containing a binary hexane-alcohol mixture of known composition, by weight, was placed in a thermostat. The mixture was titrated with water from a microburette with a scale of 0.01 mL, until opalescence, emulation or turbidity was observed. Samples of the same binary composition were titrated several times. Compositions of coexisting phases were obtained by an analytical method similar to that in [12]. Experimental points were located on the binodal curve obtained by the authors. The ternary mixture became homogeneous when the hexane concentration reached 79.4 mass % at 0 °C and 74.73 mass % at 25 °C.

Source and Purity of Materials:

1. Source not specified; purity of 99.97% for three points of the lower alcohol concentration at each temperature and purity of 92.64% for all other points.
2. Source not specified; distilled; BP = 68.65°C, $d_{4}^{20}$ = 0.6898.
3. Source not specified.

Estimated Errors:

Ambient temperature: Temp. ±0.05°C.
Mass concentration (m/v) (1): Not reported.
