Abstract
Solubility of 2-hydroxybenzoic acid (salicylic acid, with measured melting point of 432 K) in water, 1-propanol, 2-propanol, and 2-propanone was determined at (298.2 to 338.2) K and atmospheric pressure. Also, the solubility of salicylic acid in binary mixtures of 1-propanol (1) + water (2), 2-propanol (1) + water (2), and 2-propanone (1) + water (2) at 298.2 K and atmospheric pressure was investigated. Phase separation occurred in x1= 0.114, 0.167 of 1-propanol (1) + water (2) and x1= 0.171, 0.237 of 2-propanone (1) + water (2) mixtures. The van’t Hoff and Grant equations were used to correlate the solubility of salicylic acid in monosolvents at different temperatures. The solubility values of salicylic acid in binary mixtures of solvents were calculated using the Jouyban–Acree model (J. Chem. Eng. Data2009, 54, 1168–1170). The mean deviation was used as an error criterion. The overall mean deviation of correlated solubility data in monosolvents at different temperatures, and in mixed solvents at 298.2 K...
