In this work, solubility of 5-norbornene-2,3-dicarboximide (NODI) in three binary solvents (DMF + methanol, ethanol, ethyl acetate) was experimentally investigated by using laser monitoring technique at (278.15 to 323.15) K under 0.1 MPa. Solubility data of NODI increased as the temperature increased while reduced with the decreasing mass fraction of DMF. Hansen solubility parameter was employed to reveal the solubility behavior of NODI. Experimental solubility data was correlated by five thermodynamic models including NRTL, Wilson, uniquac, Margules and Jouyban-Acree-modified Apelblat (J-A-A) model. The Wilson, Margules, and uniquac model were more suitable to correlate NODI solubility than others. Besides, thermodynamic properties of mixing process (Delta(mix)G, Delta S-mix, Delta H-mix, H-1(E,infinity), in gamma(1) and in gamma(infinity)(1)) were investigated based on solubility data and the Wilson equation. Mixing processes of NODI in three binary solvents were entropy-driven. (C) 2019 Published by Elsevier B.V.
