Original Measurements

Speyers, C. L.; Am. J. Sci. 1902, 14, 293-302.

Variables:

Room Temp: 273.2 - 335.5 $\pu{K}$

Prepared by:

W.E. Acree, Jr.

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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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:
  1. Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 93.5°C.
  2. Marked “Acetonfrei”, from Kahlbaum dried over calcium oxide and distilled before use.
Estimated Errors:

Ambient temperature: T/K: precision ±0.1.
Mass concentration (m/v) (1): x1: ±8% (relative error, compiler).

Components:
  1. Acenaphthene, $\ce{ C12H10 }$; [83-32-9] NIST WebBook
  2. Methanol, $\ce{ CH4O }$; [67-56-1] NIST WebBook
