ABSTRACT

Solubilities of 2,5-furandicarboxylic acid (FDCA) in binary acetic acid + water, methanol + water and ethanol +water solvent mixtures were measured by a static analytical method with mass fraction of water in solvent varying from 0 to 0.3 at atmospheric pressure. Furthermore, the molar fusion enthalpy of FDCA (Hfus = 55.131 kJ/mol) and the fusion temperature (Tfus = 614.45 K) of FDCA were determined by the differential scanning calorimeter (DSC). The Non-Random Two Liquids (NRTL) model and the measured parameters were used to correlate these solubility data, and the relevant parameters were regressed by the least-squares method. And the NRTL model was found to provide a satisfactory representation of the experimental data.
