Methodology:
Equilibrium was established by allowing the mixtures to stand in glass stoppered flasks, with occasional shaking, for 1-3 week periods at constant temperature. Samples of the saturated aqueous solutions were withdrawn with pipettes through glass-wool plugs and transferred to separatory funnels for weighing. An extraction with cyclohexane was then performed after which the extracts were analyzed spectrophotometrically at 273 nm. The concentrations were established from previously obtained absorbance values of standard reference solutions (which were observed to obey Beer's law).
Sample Information:
- Commercial product (Matheson, Coleman and Bell), recrystallized three times from abs. ethanol, vacuum sublimed twice, UV-spectrum and melting point were determined and were identical to published data.
- Distilled and deionized water.
Measurement Errors:
Ambient temperature: ±0.5 K (authors).
Mass concentration (m/v) (1): ±2.3 (authors).
System Components:
- 1,4-Dichlorobenzene, $\ce{ C6H4Cl2 }$; [106-46-7] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
