ABSTRACT

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 temperature ranges from 273.15 K to 313.15 K by using UV spectroscopy method. The results show that solubility of ethyl vanillin increases with the increasing of temperature. Besides, the modified Apelblat equation and the eh 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 NRTL equation and the experimental solubility data.
