Components:

(1) Naphthalene, C₁₀H₈; [91-20-3] NIST WebBook
(2) Hexafluorobenzene, C₆F₆; [392-56-3] NIST WebBook

Original Measurements

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

Variables:

Ambient temperature: Temperature

Prepared by:

W.E. Acree, Jr.

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:

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