 Solubility System: Carbazole with Cyclohexane

---

Components:
   (1) Cyclohexane; C6H12; [110-82-7]  NIST Chemistry WebBook for detail
   (2) Carbazole; C12H9N; [86-74-8]  NIST Chemistry WebBook for detail

Original Measurements:
   Coon, J.E.; Sediawan, W.B.; Auwaerter, J.E.; McLaughlin, E., J. Solution Chem. 1988, 16, 519-534.

Variables:
   Temperature = Temperature

Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
320.6	0.00066	0.9993
321.1	0.00083	0.9992
325.1	0.00106	0.9989
357.2	0.00293	0.9971

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 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was used as received.
   (2) Gold Label, 99.9+ %, Aldrich Chemical Company, was used as received.

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