The solubility of pronamide in five organic solvents (ethanol, methanol, isopropanol, toluene and cyclohexane) at the temperature range from (278.15 to 323.15) K was measured by a dynamic equilibrium method. The results showed that the solubility of pronamide increased with the increasing temperature in all the solvents involved. The experimental values were correlated by the Apelblat equation, and a good fitting result was confirmed by the low level of root-mean-square deviations (less than4.0*10^-4). Moreover, the apparent dissolving enthalpies and entropies, were derived from simplified van t Hoff equation. The positive values of enthalpies and entropies revealed that the dissolution of pronamide in the selected solvents was an endothermic and entropy-driven process.
