Isobaric Vapor-Liquid Equilibrium for the Binary Systems of 1,2-Dichloroethane plus sec-Butyl Acetate, n-Propyl Acetate, and tert-Butyl Acetate at 101.3 kPa

摘要

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 with the Herington and Van Ness tests, and the regression of the VLE data for the nonrandom two-liquid, universal quasi-chemical, and Wilson activity coefficient models gave binary interaction parameters that can be used in process simulation. Both the 1,2-dichloroethane + sec-butyl acetate and 1,2-dichloroethane + n-propyl acetate binary systems exhibit positive deviations from ideality, while the 1, 2-dichloroethane + tert-butyl acetate binary system exhibits a negative deviation from ideality.
