Methodology:
Constant temperature bath, calorimetric thermometer, and an ultraviolet/visible spectrophotometer. Excess solute and solvent placed in amber glass bottles and allowed to equilibrate for several days at constant temperature. Attainment of equilibrium verified by repetitive measurements. Aliquots of saturated solutions transferred through a course filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 292 nm.
Sample Information:
- 99%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, recrystallized three times from absolute ethanol.
- Gold Label, 99+%, Aldrich Chemical Company, was stored over molecular sieves and distilled shortly before use.
Measurement Errors:
Ambient temperature: T/K: ±0.05.
Mole fraction - Liquid (1): x1: ±1.5% (relative error).
System Components:
- Carbazole, $\ce{ C12H9N }$; [86-74-8] NIST WebBook
- Cyclooctane, $\ce{ C8H16 }$; [292-64-8] NIST WebBook
