Excess properties have been a qualitative and quantitative way to predict deviation from ideality of binary liquid solution. Moreover, excess properties have been used to develop models and propose new solution theories. The present work is a continuation of an experimental study and modeling of excess molar properties of binary systems, which objective will consist in experimental determination of excess molar volume of binary liquid mixtures containing {dimethyl carbonate (DMC) + alcohol (methanol, ethanol, 1-propanol)} over the entire composition range, at different temperatures (288,15 K - 303,15 K) and at pressure range between 0,1 and 35 MPa. Excess molar volume will be determined indirectly by density measurements of pure components and respective solutions. Densities data will be obtained using a vibration-tube densimeter (Modelo DMA 4500) coupled with a high pressure cell (DMA HP) both manufactured by Anton Paar. The following binary systems will be studied: DMC + methanol, DMC + ethanol and DMC + 1-propanol. The results of densities will be used to calculate other properties, such as partial molar volume, excess partial molar volume and respective partial molar volume at infinite dilution, and apparent molar volume of each compound. Excess molar volumes data will also be used to test the applicability of Extended Real Associated Solution Model (ERAS Model). For the best of present study, there was not found any study in literature involving volumetric properties at high pressures for the systems described in this proposal. The present study is inserted in a research topic in Chemical Thermodynamics of Solution of Master's Program in Chemical Engineering of Centro Universitário da FEI (PEQ-FEI). (AU)
