ABSTRACT

Isobaric vapor-liquid equilibria (VLE) have been experimentally determined for the binary systems methanol + diethyl carbonate (DEC), ethanol + DEC, 1-propanol + DEC, 1-butanol + DEC, and DEC + 1-pentanol at 101.3 kPa. In the binary systems, the results indicate a strong positive deviation from ideality and a single minimum temperature azeotrope corresponding to the binaries 1-butanol and 1-pentanol with DEC. The results were tested for thermodynamic consistency and were satisfactorily correlated with the Wilson and UNIQUAC equations. Our interaction parameters in the ASOG and UNIFAC methods, for the carbonate group (-OCOO-) and alcohols (-OH), were used to predict our experimental VLE data.
