Solubility modeling, mixing properties and solvent effect of 5-norbornene-2,3-dicarboximide in eleven pure solvents at various temperatures

Mole-fraction solubility of 5-norbornene-2,3-dicarboximide (NODI) in eleven solvents including methanol (MtOH), ethanol (EtOH), 2-ethoxyethanol, methyl acetate (MAC), ethyl acetate (EAC), n-propyl acetate (NPAC), isopropyl acetate (IPAC), n-butyl acetate (NBAC), acetone (DMK), N,N-dimethylformamide (DMF) at (278.15-323.15) K and 1,4-dioxane at (288.15-323.15) K was experimentally measured by laser monitoring technique under 0.1 MPa. Solubility of NODI increased with the increasing temperature. Hansen Solubility Parameter was employed to explain the solubility behavior. The Kamlet-Taft parameters were calculated to investigate the solvent effect based on linear solvation energy relationships concept. Thermodynamic modeling including the Two-Suffix Margules model, Wilson model, NRTL model, NRTL-SAC model and UNIQUAC model were employed to correlate the experimental solubility. Wilson model and NRTL-SAC model were more suitable in correlation with solubility data. Furthermore, thermodynamic properties of mixing process (Delta(mix)G, Delta H-mix, Delta S-mix, ln gamma(infinity)(1), H-1(E,infinity), zeta(TS )and zeta(H)) were discussed based on Wilson equation.
