Glass Ball as Bullet Solubility System: Acenaphthene with Ethanol

Components:
   (1) Ethanol; C2H6O; [64-17-5]  NIST Chemistry WebBook for detail
   (2) Acenaphthene; C12H10; [83-32-9]  NIST Chemistry WebBook for detail

Original Measurements:
   Speyers, C.L., Am. J. Sci. 1902, 14, 293-302.

Variables:
   Temperature = Temperature

T/KMole Fraction x1Mole Fraction x2

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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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 absolute, from Eimer and Amend and Chas. Cooper and Co., dried over calcium oxide and distilled before use.

Estimated Errors:
   Solubility: x1: ± 8 % (relative error, compiler).
   Temperature: T/K: precision ± 0.1.
