ABSTRACT

The solubility of borneol, camphor and isoborneol in four solvents (i.e. acetone, ethanol, p-cymene and p-xylene) was measured by the static equilibrium method within the temperature range of (296.65 to 348.85) K at atmosphere. The fusion points and fusion enthalpies of borneol and isoborneol were determined by differential scanning calorimetry (DSC). The Apelblat equation, Wilson model and NRTL model were employed to correlate the measured solubility data, and the NRTL model fits the measured data better. Mixing properties of each solute-solvent pair are calculated by the NRTL model.
