 Solubility System: Acenaphthene with Pyridine

---

Components:
   (1) Pyridine; C5H5N; [110-86-1]  NIST Chemistry WebBook for detail
   (2) Acenaphthene; C12H10; [83-32-9]  NIST Chemistry WebBook for detail

Original Measurements:
   Choi, P.B.; McLaughlin, E., Ind. Eng. Chem. Fundam. 1983, 22, 46-51.

Variables:
   Temperature = Temperature

   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
306.7	0.2102	0.7898
320.0	0.3166	0.6834
332.9	0.4592	0.5408
337.5	0.5191	0.4809
343.7	0.6110	0.3890

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 %, British Drug Houses, United Kingdom, was recrystallized and then zone refined.
   (2) Gold Label, 99.9+ %, Aldrich Chemical Company, was used as received.

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