Method/Apparatus/Procedure:
The 1,3-dichlorobenzene was mixed with water in a sealed flask (1) with the aid of a magnetic stirrer for 48 hours in a water bath at constant temperature. After the solution was filtered through a glass-wool plug, the solute was extracted with 2, 2, 4-trimethylpentene. The optical density of each sample was determined spectrophotometrically (2). Mean and standard deviations were calculated from three measurements.
Source and Purity of Materials:
- Fluka AG, puriss, >99% GLC, used as received.
- Distilled, deionized, and degassed.
Estimated Errors:
Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±1.93%.
