Components:
   (1) Hexaflourobenzene; C6F6; [392-56-3]  NIST Chemistry WebBook for detail
   (2) Naphthalene; C10H8; [91-20-3]  NIST Chemistry WebBook for detail

Original Measurements:
   McLuaghlin, E.; Messer, C.E., J. Chem. Soc., Sect. A 1966, 1106-1110.

Variables:
   Temperature = Temperature

Prepared By:

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
346.80	0.8823	0.1177
348.30	0.9105	0.0895
349.80	0.9353	0.0647
351.75	0.9707	0.0293

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) Molecular Weight Grade, Hopkin and Williams, was passed over an alumina column, recrystallized and sublimed.
   (2) Purity not given, Imperial Smelting, Ltd., Avonmouth, Bristol, was dried over anhydrous calcium sulfate.

Estimated Errors:

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