Original Measurements

Komarova. E. G.; Kogan, V. B.; Zh. Prikl. Khim. 37, 1776-86 (1964).

Variables:

Room Temp: 293 - 343 $\pu{K}$

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The analytical method was used. Mixtures of (1), (2) and (3) was placed in a thermostated cell and stirred for an hour. The composition of the phases was determined by gas chromatography.

Source and Purity of Materials:
  1. Source not specified, pure grade reagent; distilled in 1.2 m fractionating column; BP = 101.2°C; $n_{D}^{20}$ = 1.3818, $d_{4}^{20}$ = 1.1380.
  2. Source not specified, pure grade reagent; distilled in 1.2 m fractionating column; BP = 114.0°C; $n_{D}^{20}$ = 1.3920, $d_{4}^{20}$ = 1.0520.
  3. Source not specified; pure grade reagent; distilled in 1.2 m fractionating column; BP = 98.4°C; $n_{D}^{20}$ = 1.3877, $d_{4}^{20}$ = 0.6838.
Estimated Errors:

Ambient temperature: control to ±0.1 K.
