Source Publication

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

Conditions:

Room Temp: Temperature $\pu{K}$

Compiler:

W.E. Acree, Jr.

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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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:
  1. Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 80.1°C.
  2. Purity not given, Kahlbaum, was distilled before use.
Measurement Errors:

Ambient temperature: T/K: precision ±0.1. x1: ±8% (relative error, compiler).

System Components:
  1. Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
  2. Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
