Solubility of salicylic acid in ethanol, acetone and ethyl acetate solvents at temperature ranging from 298 to 313K

In this study, the solubilities of salicylic acid in ethanol, acetone, ethyl acetate solvents at temperature ranging from 298 to 313 K were measured by gravimetrical method under atmospheric pressure. The results showed that the solubilities of salicylic acid increase with increasing temperature. The Modified Appellate equation, ʎh equation, Wilson equation and NRTL equation were used to correlate the solubility results [1-3]. That NRTL was the best model for correlation of the solubility data. All experimental solubility data and interaction parameters will be used as key information to chemical thermodynamic modeling and as reference in process/ product development
