摘要：

The solubility data of ethyl vanillin in binary solvents, including (propan-2-one + water), (methanol + water), (ethanol + water), and (propan-2-ol + water), were measured in the temperature range from 273.15 to 313.15 K by using a UV spectroscopy method. The results show that the solubility of ethyl vanillin increases with increasing temperature. Besides, the modified Apelblat equation and the Ah equation were used to correlate the experimental solubility data. Dissolution thermodynamic properties of ethyl vanillin in different binary solvent mixtures, including Gibbs energy, enthalpy, and entropy, were calculated based on the nonrandom two-liquid equation and the experimental solubility data.
