Glass Ball as Bullet Solubility System: Coronene with n-Heptane

Components:
   (1) n-Heptane; C7H16; [142-82-5]  NIST Chemistry WebBook for detail
   (2) Coronene; C24H12; [191-07-1]  NIST Chemistry WebBook for detail

Original Measurements:
   Lissi, E.A.; Abuin, E.B., Bol. Soc. Chil. Quim. 1981, 26, 19-34.

Variables:
   Temperature = 293 K

Prepared By:
   W. E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  
t/°CConcentration c1 [mol dm**-3]
20.00.00048
Method/Apparatus/Procedure:
   Constant temperature bath, centrifuge, thermometer, and a spectrofluorimeter. Excess solute and solvent were placed in glass vials, pre-equilibrated for several hours at 60-80 °C, and then equilibrated at 20 °C for several additional hours. After equilibration and  centrifugation, concentrations determined from the measured fluorescence emission intensity.

Source and Purity of Materials:
   (1) Purity not given, commercial sample of unspecified source, was used as received.
   (2) Purity and chemical source were not given, purification procedure not specified.

Estimated Errors:
   Solubility: c1: ± Unknown.
   Temperature: T/K: ± 2.
