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. (C) 2019 Elsevier B.V.
