Original Measurements
Acree Jr., W. E.; Pontikos, N. M.; Judy, C. L.; Int. J. Pharm. 1986, 31, 225-230.
Variables:
Room Temp: 303, 308 and 313 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
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 cyclohexane. Concentrations determined spectrophotometrically at 250 nm.
Source and Purity of Materials:
- 99%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, recrystallized three times from methanol.
- 99.8+%, Spectroanalyzed, Fisher Scientific, Pittsburgh, Pennslvania, USA, was stored over molecular sieves and distilled shortly before use.
Estimated Errors:
Ambient temperature: T/K: ±0.05.
Mole fraction - Liquid (1): x1: ±1% (relative error).
Components:
- Biphenyl, $\ce{ C12H10 }$; [92-52-4] NIST WebBook
- Tetrachloromethane, $\ce{ CCl4 }$; [56-23-5] NIST WebBook
