Variables:

Room Temp: 298 $\pu{K}$

Prepared by:

A. Skrzecz

Method/Apparatus/Procedure:

The cloud point method was used to determine the solubility curve. The experimental apparatus was described in [1]. The analytical method was used to determine liquid-liquid equilibria. Mixtures of known overall composition, by weight, were stirred intensely and allowed to settle for 2 h at constant temperature bath. Samples of each phase were taken and analyzed by GLC method with 1-propanol as internal standard. (1-propanol also prevented phase separation.) Analytical conditions: column 2 m x 3 mm, packed with Chromosorb 101 100/120, temp. 190 °C, thermal conductivity detector for the organic phase, flame ionization detector for aqueous phase, helium flow rate - 40 mL/min. Water was reported to be undetectable in the organic phase.

Source and Purity of Materials:

1. Merck, used as received; <0.2 wt% impurities by GLC.
2. Merck, used as received; mixture of cis- and trans-isomers.
3. Source not reported.

Estimated Errors:

Ambient temperature: Temp. ±0.1°C; relative accuracy of composition 2% (solubility curve).
Mass concentration (m/v) (1): Not reported.
