---

Components:
   (1) 1,2,3,4-Tetrahydronaphthalene; C10H12; [119-64-2]  NIST Chemistry WebBook for detail
   (2) Acenaphthene; C12H10; [83-32-9]  NIST Chemistry WebBook for detail

Original Measurements:
   Coon, J.E.; Auwaerter, J.E.; McLaughlin, E., Fluid Phase Equilibr. 1989, 44, 305-345.

Variables:
   Temperature = Temperature

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
308.1	0.2521	0.7479
312.6	0.2849	0.7151
322.2	0.3641	0.6359
331.9	0.4695	0.5305
343.7	0.6175	0.3825
351.9	0.7461	0.2539

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) 99.2 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was passed over an activated alumina column and then recrystallized from solution.
   (2) 99.6+ %, Aldrich Chemical Company, was stored over molecular sieves to remove trace water.

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