Abstract:
The isobaric vapor?liquid equilibrium (VLE)
behaviors for binary system, ethyl acetate ? ethyl benzene,
and ethyl acetate ? ethyl benzene ? LiBr (at saturation)
were studied at the local ambient pressure (707 ? 1 mmHg).
Equilibrium still was used where both liquid and vapor were
continuously circulated. The experimental results showed
that salt-free ethyl acetate ? ethyl benzene system does not
form an azeotrope point. The experimental results for ethyl
acetate ? ethyl benzene system were in a very good agreement
with the predicted results using UNIFAC, UNIQUAC,
NRTL, and Wilson models. Adding LiBr, as a salt, did show
slight effects on the VLE behavior of ethyl acetate ? ethyl
benzene system.
