ABSTRACT

The solubility of benzoic acid and acetylsalicylic acid is reported in varied pure solvents over a range of 275.39 327.03 K and 275.12 327.91 K for benzoic acid and aspirin, respectively, using the polythermal method with a heating rate of 0.1 K/min that was combined with the Lasentec focused beam reflective measurement to determine the saturation point of the solutions. The results were correlated using a modified van t Hoff equation that fitted the solubility with a 2 K interval over a temperature range of 278.15 323.15 K. The results from the fitting equation were in good agreement with the experimental data.
