Abstract

The present work reports experimental data of the solubility of α-lactose in solutions of water-ethanol-NaCl and water-ethanol-CaCl₂ at 298.15 K. For low ethanol contents, the salts decrease the solubility of α-lactose, whereas for high ethanol contents the salts increase the solubility of α-lactose. The experimental solubility data are successfully modeled using two approaches, both of which are based on the UNIQUAC model. A modified UNIQUAC model extended by a Debye-Hückel term as well as a UNIQUAC model extended by a general perturbation scheme are used.
