Methodology:
Constant temperature bath, analytical balance and high pressure equipment.
Excess solute and solvent allowed to equilibrate in a specially designed high pressure cell at constant temperature for 20-24 hours. Known amount of saturated solution removed, solvent evaporated to dryness, and concentration determined from weight of solid residue.
Sample Information:
- Purest grade, Eastman Kodak Chemical Company, Rochester, New York, USA, was used as received.
- Pure grade, Phillips Petroleum, was dried over phosphorous pentoxide and distilled.
Measurement Errors:
Ambient temperature: T/K: ±precision 0.1. x1: ±1-3% at atmospheric pressure, and ±10% at the higher pressures.
System Components:
- Phenanthrene, $\ce{ C14H10 }$; [85-01-8] NIST WebBook
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
