Original Measurements
Speyers, C. L.; Am. J. Sci. 1902, 14, 293-302.
Variables:
Room Temp: 237.2 - 344.8 $\pu{K}$

Method/Apparatus/Procedure:
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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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.
Source and Purity of Materials:
- Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 93.5°C.
- Marked absolute, from Eimer and Amend and Chas. Cooper and Co., dried over calcium oxide and distilled before use.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±8% (relative error, compiler).
Components:
- Acenaphthene, $\ce{ C12H10 }$; [83-32-9] NIST WebBook
- Ethanol, $\ce{ C2H6O }$; [64-17-5] NIST WebBook
