Original Measurements

Kotarski, A.; Przem. Chem. 42, 413 (1963).

Variables:

Room Temp: 293 $\pu{K}$

V.P. Sazonov

Method/Apparatus/Procedure:

The solubility curve was determined by the method of Rifai and Durandet [1]. The analytical method was used to determine coexisting liquid phase compositions. A known weight of a two-phase mixture was equilibrated in a thermostat, separated, liquid phases weighed, and the refractive index of coexisting phases measured. Concentrations of [1] and (3) in both phases were measured using calibrated plots, which allowed determination of coexisting phase compositions.

Source and Purity of Materials:
  1. Source not specified; dried over molecular sieve and distilled; $n_{D}^{20}$ = 1.3820.
  2. Source not specified; dried over molecular sieve and distilled; $n_{D}^{20}$ = 1.4968.
  3. Source not specified; purified on silica gel and fractionally distilled; $n_{D}^{20}$ = 1.4233, $d_{4}^{20}$ = 0.7695 .
Estimated Errors:

Mass concentration (m/v) (1): titer: ±0.005 mL.
