Abstract

Isobaric vapour-liquid equilibrium data have been measured for the binary systems toluene (1)+acetic acid (2) and toluene (1)+methyl ethyl ketone (2) at atmospheric pressure. An all-glass Fischer-Labodest-type apparatus, capable of handling pressures from 0.25 to 400 kPa and temperatures up to 523.15K was used. The data were correlated by means of the NRTL, UNIQUAC, WILSON models and the applied UNIFAC model with satisfactory results; the relevant parameters are given and results were tested with regard to thermodynamic consistency using the methods of a modified Redlich-Kister and Herington equations.
