Glass Ball as Bullet Solubility System: Carbazole with 1-Octanol
Components:
   (1) 1-Octanol; C8H18O; [111-87-5]  NIST Chemistry WebBook for detail
   (2) Carbazole; C12H9N; [86-74-8]  NIST Chemistry WebBook for detail
Original Measurements:
   Anderson, B.D., Ph.D. Dissertation, University of Kansas, Lawrence, Kansas, USA (1978).

 Variables:
   Temperature = 298 K

   W. E. Acree, Jr.

 Experimental Data:   (Notes on the Nomenclature)
  
t/°CConcentration c1 [mol dm**-3]
25.00.0515
 Method/Apparatus/Procedure:
   Constant temperature bath, rotator, thermometer, and an ultraviolet/visible spectrophotometer. Excess solute and solvent placed in glass vials and allowed to equilibrate for several days at constant temperature. Attainment of equilibrium verified by repetitive measurements.  Aliquots of saturated solutions transferred through a course filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 356 nm.

 Source and Purity of Materials:
   (1) 99+ %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was recrystallized from acetone-heptane mixtures.
   (2) 99+ %, Aldrich Chemical Company, was stored over molecular sieves to remove trace water.

 Estimated Errors:
   Solubility: c1: ± 3 % (relative error, compiler).
   Temperature: T/K: ± 0.1 (compiler).
