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]
20.00.00037
 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 ºC, and then equilibrated at 20 ºC 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 not given, purification procedure not specified.

 Estimated Errors:

   Temperature: T/K: ± 2. c1: Unknown.
