 Solubility System: Acenaphthene with Decahydronaphthalene

---

Components:
   (1) Decahydronaphthalene; C10H18; [91-17-8]  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

   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
300.7	0.1239	0.8761
310.9	0.1873	0.8127
318.7	0.2496	0.7504
327.8	0.3302	0.6698
336.0	0.4477	0.5523
348.3	0.6597	0.3403

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+ %, Aldrich Chemical Company, having isomer ratio of 60.6 % cis and 39.4 % trans, stored over molecular sieves.

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