Isobaric Vapor Liquid Equilibrium Data for the 1,2-Dichloroethane–1-Butanol System

Abstract

Boiling points for 1,2-dichloroethane and 1-butanol were determined, and P–T–x data for the binary mixture were measured under isobaric conditions using a modified ebulliometer in the pressure range of (101.325 to 60.0) kPa. The pure component experimental vapor pressure data were modeled using Antoine, Wagner, and Thomas models and compared with the literature values. The modeling of binary VLE data was done using Margules 3-suffix, Wilson, and NRTL models. The average RMSD(T) values based on the literature and model predictions for the pure components are in the ranges of (0.42 to 0.47) K and (0.03 to 0.08) K, respectively. Similarly, for the binary system the average RMSD(T) value based on the model prediction is 0.33 K.
