| Summary: | 碩士 === 國立中央大學 === 化學工程學系 === 86 === The aim of this study will probe into the thermodynamic
behavior of acetic acid,isoamyl alcohol,water,isoamyl acetate
mixture,during manufacturing the specialtychemical,isoamyl
acetate by reactive distillation process.This approach is
consideringthe chemical reaction equilibrium and phase
equilibrium simultaneously. The experiments of chemical
equilibrium and phase equilibrium were conducted in a modified
Othmer type equilibrium cell.The commercial NaY catalyst(Y
typezeolite)was added to increase chemical reaction rate,and
found no effect on thephase equilibrium.51 experimental data
were collected for this study. The experimental VLE data were
correlated by activity coefficient models ofUNIQUAC,NRTL,Wilson
respectively,with consideration of the strongly associationof
acetic acid molecules in vapor phase.Our calculated results show
that the correlation by UNIQUAC model was in good agreement with
the experimental data.It is also found that the reactive
azeotrope does not exist in this study byusing Barbosa and
Doherty's criterion of a reactive system[5].
