Glass Ball as Bullet Solubility System: Carbazole with Butyl butyrate
Components:
   (1) Butyl butyrate; C8H16O2; [109-21-7]  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

 Experimental Data:   (Notes on the Nomenclature)
  
t/°CConcentration c1 [mol dm**-3]
25.00.0994
 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) Purity not given, Eastman Chemical Co., Rochester, New York, USA, was shaken with sodium hydroxide, washed with distilled water, dried over magnesium sulfate and distilled. Stored over molecular sieves and distilled shortly before use.

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