Components:
   (1) 1-Propanol; C3H8O; [71-23-8]  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

Prepared By:
   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
273.2	0.0088	0.9912
283.7	0.0097	0.9903
304.3	0.0188	0.9812
323.5	0.0437	0.9563
346.6	0.199	0.801

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 Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity.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) Purity not given, Kahlbaum, was dried over calcium oxide and distilled before use.

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