dc.description.abstract(Solid + liquid) equilibria of binary mixtures containing high-value compounds and ethyl lactate werestudied. Using the gravimetric method, the solubility of various solutes such as caffeine, vanillic acid,ferulic acid, caffeic acid and thymol in ethyl lactate was measured as a function of temperature overthe range of (298.2 to 343.2) K, at atmospheric pressure. The differences in solubility of a given solutein water-saturated and dry ethyl lactate were observed. The deviation of these binary systems from idealmixture behaviour was discussed. In order to understand the solubilization process, melting properties ofpure solutes were determined by differential scanning calorimetry (DSC). The solubility data obtainedwere represented using UNIQUAC and UNIFAC-based models as well as with the Cubic-Plus-Association(CPA) equation of state. The results of the modeling indicate that these models are the appropriate toolsfor representing the solubility behaviour of various solutes in ethyl lactate. 2011 Elsevier Ltd. All rights reserved
