Isothermal Vapor-Liquid Equilibria for Binary and Ternary Systems Containing Ethyl tert-Butyl Ether, Ethanol, Benzene, and Toluene at 313.15 K

Isothermal vapor-liquid equilibrium data are reported for the binary systems of ETBE + ethanol, ETBE + benzene, ETBE + toluene, ethanol + benzene. and ethanol + toluene using the HSGC static measuring method at 313.15 K. These data show positive deviations from Raoult`s law. The binary systems of ETBE + benzene and ETBE + toluene possess no azeotropic points. while ethanol-containing binary mixtures have minimum boiling azeotropes at the measured temperature. All the binary systems can be correlated well with common g^E model equations within 1% of the deviation of the vapor mole concentration. The VLE data were also predicted by the modified UNIFAC (Dortmund) model for the same systems and temperature. The deviations of the vapor phase mole fractions between the predicted and measured values were less than 2% for almost all of the systems. In addition, ternary VLE data for the systems ETBE + ethanol + benzene and ETBE + ethanol + toluene were calculated using the fitted Wilson parameters of the measured constituent binary systems, and also they were predicted using the modified UNIFAC (Dortmund) model.
