ABSTRACT

Isobaric vapor-liquid equilibrium (VLE) data at 101.3 kPa for three binary systems, which are 1,2-dichloroethane + sec-butyl acetate, 1,2-dichloroethane + n-propyl acetate and 1,2-dichloroethane + tert-butyl acetate, were reported in this work. The thermodynamic consistency of all experimental data was performed by the Herington and Van Ness test. And the regression of the VLE data for the nonrandom two-liquid, universal quasichemical and Wilson activity coefficient models gave binary interaction parameters, which can be used in process simulation. Both of the 1,2-dichloroethane + sec-butyl acetate and 1,2-dichloroethane + n-propyl acetate binary systems exhibit positive deviation from ideality, while 1,2-dichloroethane + tert-butyl acetate binary system exhibits negative deviation from ideality. 1.
