摘要：
Isobaric vapor-liquid equilibrium (VLE) data are reported for binary mixtures of methyl formate + o-xylene, methyl formate + m-xylene, methyl formate + p-xylene, and methyl formate + ethylbenzene at 101.33 kPa. The data are obtained using a vapor recirculating type (modified Othmer's) equilibrium still. All of the binary systems show positive deviation from ideality. None of the systems form an azeotrope. The VLE data for these binary systems are checked to meet rigorous thermodynamic consistency by the Herington method and the point-to-point test of the Fredenslund method. The experimental VLE data are well-correlated by the nonrandom two-liquid (NRTL), universal quasichemical activity coefficient (UNIQUAC), and Wilson equations.
