| Title: | Solubility of multifunctional associating molecules: measurements and thermodynamic modeling |
| Issue Date: | 2008 |
| Description: | Numerous molecules in the pharmaceutical, food and chemical industries presentcomplex chemical structures with different functional group substitutions. Many of thesegroups such as amine, carboxyl and hydroxyl can form hydrogen bonds. To adequatelydescribe the phase equilibria of these complex chemicals, models able to take intoaccount association effects are required. Still, for model development and evaluation,experimental data on some representative systems are needed. In this work, newexperimental measurements and literature data were combined to develop amethodology to model the phase equilibria of phenolic acids using the Cubic-plusAssociation(CPA) equation of state. A comparison with the UNIQUAC activitycoefficient model is also presented. Within the different classes of multifunctionalassociating molecules, phenolic compounds, due to their chemical and biologicalimportance, are among the most important. Apart from being starting materials formany chemical syntheses, there is also huge evidence that some phenolic compoundshave beneficial effects on human health. |
