Solubility of salicylic acid in ethanol, propylene glycol, and N-methyl-2-pyrrolidone at various temperatures and their binary mixtures at 298.2 K

Abstract

Solubility of salicylic acid in ethanol (EtOH), propylene glycol (PG), and N-methyl-2-pyrrolidone (NMP) at temperatures of 298.2, 308.2, 318.2, and 328.2 K and in the binary mixtures of EtOH + PG, NMP + EtOH, and NMP + PG were reported at 298.2 K. The generated data in mono-solvents at different temperatures were fitted to van't Hoff plot, the data in solvent mixtures were fitted to the Jouyban-Acree model, and the overall mean deviations were 3.5 and 0.8%, respectively.
