ABSTRACT

Isobaric vapor-liquid equilibria have been measured with a vapor recirculating type (modified Othmer s) equilibrium still for the system, vinyl acetate + p-xylene at 97.3 kPa. The system deviates positively from ideal behavior and does not have an azeotrope. The thermodynamic consistency of the experimental data was checked by Herington, Black, and Hirata tests. The activity coefficients were correlated by means of the Margules, Redlich-Kister, Black, and Wilson equations. A comparison of values of activity coefficients obtained by experimental data was made with UNIFAC model. Also the excess molar volumes, viscosities, and speeds of sound for the binary mixture at T ) (303.15, 308.15, and 313.15) K have been determined for the whole compositional range. The deviations in viscosity and excess isentropic compressibility have also been estimated. All of the excess properties have been fitted to the Redlich- Kister equation.
