Resumo
In 2009 we have started a project on Centro de Química Estrutural in the Faculty of Sciences of the Lisbon University for studying thermodynamic properties and behaviors of alcoholic mixtures at elevated temperatures. Because VLE measurements at elevated temperatures show some experimental difficulties due to the possible thermal degradation of some alcohols, like methanol, a flow apparatus was chosen in order to minimize this phenomenon. Over the years several modifications were made to the equipment, upgrading not only its operation but also and more important its\naccuracy. Several binary and ternary mixtures of alcohol and water have been studied [1-4]. Because the chosen temperatures not always have available data to compare, several theories were used in order to “validate” the good performance of the apparatus.\nThe changes in the equipment, the binary and ternary data obtained as well as the consistency tests made to these sets of experimental data are presented here and discussed.\nFinally, because validation normally requires a reference material, we intend to effectively validate the equipment and its procedure following the IUPAC project 2011-037-2-100 entitled “RECOMMENDED REFERENCE MATERIALS FOR PHASE EQUILIBRIUM STUDIES”. This fact is also discussed here and its advantages to our project of VLE measurements are mention.
