Keywords:
Imidazole, Solubility, Apelblat equation, NIBS, Solution thermodynamics.Abstract
Solubility of imidazole in water, methanol and in water-methanol binary mixtures have been experimentally measured using a gravimetric method at temperatures (293.15, 295.15, 298.15, 300.15, 303.15, 305.15, 308.15, 310.15 & 313.15) K. Solubility values were correlated by the Apelblat equation. The combined NIBS (nearly ideal binary solvent)-Redlic-Kister equation is used to fit experimental solubility data at constant temperature. Thermodynamic functions including , , and of solution of imidazole are obtained from the modified van’t Hoff equation.
