Components:
   (1) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
   (2) Naphthalene; C10H8; [91-20-3]  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
308.2	0.3766	0.6234
318.2	0.4806	0.5194
320.6	0.5094	0.4906
336.4	0.7119	0.2881
349.0	0.9180	0.0820

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 given, British Drug Houses, United Kingdom, was passed over an alumina 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).
