In present work, the concentration and temperature dependence of the thermodynamic properties of3-substituted Schiff base of 4-piperidyl N-(4-chlorophenyl)maleimide compound in 80% DMSO wasestimated. Concentration (0.002-0.01 M) and temperature (298-313 K) dependent densitometric andviscometric measurement were employed to evaluate limiting molar volume (φv0), semi-empiricalparameter (Sv), Falkenhagen (A) and Jones-Dole (B) viscosity coefficient. The obtained results suggestthe presence of weaker solute-solvent interactions and stronger solute-solute interactions. It was observedthat these interactions strongly depend on the temperature of the system. Furthermore, the Gibbs freeenergy (ΔG), enthalpy (ΔH) and entropy (ΔS) of the system were also evaluated. The negative values ofΔG and ΔH and positive values of ΔS indicating reaction was spontaneous and exothermic in nature.
