| dc.description.abstract | Diethyl carbonate (DEC) is widely used as a solvent in natural resin synthesizing and in textile dyeing, as a fuel additive to reduce the emission of carbon dioxide, and as a solvent for electrolytic solution in the capacitor and lithium battery, because of its electrochemical stability,
permittivity, dissociation capability, lower vapor pressure, and good solubility in gasoline. The vapor pressure of diethyl carbonate and the vapor-liquid equilibrium (VLE) of its mixtures are important information for all these applications.
In this work, an apparatus is set up to measure isobaric VLE at atmospheric pressure and validated by studying the binary mixture of DEC + ethanol. Then, we will conduct a systematic study on binary VLE of DEC + 2-butanol, 2-methyl-2-propanol at atmospheric pressure. All
these measuring data will be checked with the thermodynamic consistency test. Furthermore, the measured results will compare with calculated results from predictive thermodynamic models (COSMO-SAC and UNIFAC) and correlative thermodynamic models (UNIQUAC and NRTL) with binary interaction parameters obtained from regression of newly measured experimental data. | en_US |
