Methodology:
Approximately 50 mL of (1) together with (2) were placed in a 125 mL hypo-vial which was closed with a teflon coated rubber septum and placed in a constant-temperature water bath. The system was stirred magnetically for 24 hr and left in the bath for three days or was kept in the bath without stirring for seven days, before samples were taken for analysis.
The solubility of water in the organic layer was determined by Karl Fischer titration and the solubility of hydrocarbon in the water layer was determined by gas chromatography.
Sample Information:
- Phillips Petroleum Co.; pure grade reagent (99+%); shaken three times with distilled water.
- distilled.
Measurement Errors:
Ambient temperature: (a) ±0.02 K, (b) ±0.01 K
Mass concentration (m/v) (1): (c) ±1.7%, (d) ±4.7%, (e) ±3.1% (from two or three determinations)
System Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
