Liquid–liquid
equilibrium (LLE) data for the ternary system
water + benzyl alcohol + methylbenzene were measured at (303.2 to
343.2) K under atmospheric pressure. The Othmer–Tobias and
the Hand correlations were used to check the reliability of the experimental
LLE data. The distribution coefficient and separation factor were
used to investigate the ability of water to extract benzyl alcohol
from methylbenzene. The results show that the distribution coefficient
of benzyl alcohol increases with the increasing mass fraction of water
in the aqueous phase. The experimental data were correlated by both
the nonrandom two-liquid (NRTL) and the universal quasichemical (UNIQUAC)
activity coefficient models. The relevant model interaction parameters
were regressed by data fitting. The model calculated results show
good agreement with the measured data. The obtained interaction parameters
can be used in the calculation of LLE for the ternary system water
+ benzyl alcohol + methylbenzene as well as for the design and optimization
of the related separation process.
