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 coarse filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 356 nm.
Sample Information:
- Gold Label, 99.9+%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, used as received.
- 99+%, anhydrous, 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:
- Anthracene, $\ce{ C14H10 }$; [120-12-7] NIST WebBook
- 2-Propanol, $\ce{ C3H8O }$; [67-63-0] NIST WebBook
