Conditions:
Room Temp: 273.2 - 335.5 $\pu{K}$
Compiler:
Methodology:
Experimental procedure only marginally described by author. Excess solute and solvent were equilibrated in a constant temperature water bath for between 10-30 minutes. Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity. Author noted that evaporation to dryness and weighing the residue was subject to too much decomposition.
Sample Information:
- Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 93.5°C.
- Marked “Acetonfrei”, from Kahlbaum dried over calcium oxide and distilled before use.
Measurement Errors:
Ambient temperature: T/K: precision ±0.1.
Mass concentration (m/v) (1): x1: ±8% (relative error, compiler).
System Components:
- Acenaphthene, $\ce{ C12H10 }$; [83-32-9] NIST WebBook
- Methanol, $\ce{ CH4O }$; [67-56-1] NIST WebBook
