Conditions:
Room Temp: 293 $\pu{K}$
Compiler:
Methodology:
Constant temperature bath, thermometer, and a precision balance.
Excess solute and solvent placed in closed glass container and allowed to equilibrate for several hours at constant temperature. Aliquots of saturated solutions were transferred into tared containers and weighed. Solubilities calculated from weight of solid residue that remained after solvent had evaporated.
Sample Information:
- 95% initial purity, source not given, was recrystallized several times from toluene and ethanol to give a melting temperature of 150.5-150.9°C.
- 99%, Urxovy Zavody, Czech., was used as received.
Measurement Errors:
Ambient temperature: T/K: precision ±0.05. x1: ±3% (relative error; compiler).
System Components:
- Pyrene, $\ce{ C16H10 }$; [129-00-0] NIST WebBook
- Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
