Isobaric vapor-liquid equilibrium at 101.3 kPa and excess properties at 298.15 K for binary mixtures of methyl phenyl carbonate with methanol or dimethyl carbonate
The vapor pressure of the pure component of methyl phenyl carbonate (MPC) was measured at temperatures ranging from 378 K to 488 K. The experimental vapor pressures could be fit well with a three-parameter Antoine equation. Isobaric vapor-liquid equilibria for binary systems (MPC+ methanol and MPC+ dimethyl carbonate) were determined using a dynamic method at 101.3 kPa. They were correlated with Wilson, NRTL and UNIQUAC models. In addition, excess molar volumes (V-E) and deviations in molar refractivity (Delta R) at 298.15 K were recorded for the same binary systems using a digital vibrating tube densitometer and a precision digital refractometer. The V-E and Delta R data were in good agreement with the predictions of the Redlich-Kister equation. (C) 2013 Elsevier B.V. All rights reserved.
