 Solubility System: Acenaphthene with Cyclohexane

---

Components:
   (1) Cyclohexane; C6H12; [110-82-7]  NIST Chemistry WebBook for detail
   (2) Acenaphthene; C12H10; [83-32-9]  NIST Chemistry WebBook for detail

Original Measurements:
   McLaughlin, E.; Zainal, H.A., J. Chem. Soc. 1960, 3854-3857.

Variables:
   Temperature = Temperature

Prepared By:
   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
308.7	0.0880	0.9120
323.2	0.2077	0.7923
330.2	0.2812	0.7188
334.0	0.3453	0.6547

Method/Apparatus/Procedure:
   Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by noting the temperature at which the  last trace of solid solute disappeared.

Source and Purity of Materials:
   (1) Purity note given, Gesellschaft fur Teerverwertung, was passed over an alumina column with benzene as eluant.
   (2) Purity, source and purification method was not specified.

Estimated Errors:
   Solubility: x₁: ± 0.0003 (compiler).
   Temperature: T/K: precision ± 0.1.
