Components:
   (1) Phenanthrene; C14H10; [85-01-8]  NIST Chemistry WebBook for detail
   (2) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail

Original Measurements:
   McLaughlin, E.; Zainal, H.A., J. Chem. Soc. 1959, 863-867.

Variables:
   Temperature = Temperature

Prepared By:
   W.E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
305.2	0.2239	0.7761
313.4	0.2836	0.7164
315.0	0.2990	0.7010
323.4	0.3750	0.6250
331.2	0.4572	0.5428

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 visual noting the same temperature at which the last trace of solid solute disappeared.

Source and Purity of Materials:
   (1) Purity not specified, Bureau of Mines, USA, was passed over an alumina column with benzene as eluant.
   (2) "AnalaR", was dried over sodium wire and freshly distilled before use.

Estimated Errors:

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