Notes:
     ø2(s): initial volume fraction of binary solvent mixture; c1: molar solubility (mol dm-3) of the solute.

Method/Apparatus/Procedure:
   Constant temperature bath, calorimetric thermometer, and an HPLC equipped with fluorescence detection. Binary solvent mixtures were prepared by volume. Excess solute and solvent placed in glass vials and allowed to equilibrate with rotation for 12-24 hours in a constant temperature bath.  Prior to analysis samples were centrifuged at 300 RCF for 15 minutes. The clear supernatant solutions were analyzed by reversed-phase liquid chromatography with fluorescence detection. Excitation and emission filters employed were 350 nm and 420 nm, respectively.  An octadecylsilanized stationary phase and a acetonitrile-methanol-water mobile phase were used in the chromatographic analysis.
