Vapor-liquid equilibria of selected components in propylene oxide production
Vapor-liquid equilibrium (VLE) of binary systems formed by 1,2-dichloropropane and propylene chlorohydrine or bis(2-chloroisopropyl) ether at a pressure of 10 kPa as well as the variation of the saturated vapor pressure of propylene chlorohydrine and bis(2-chloroisopropyl) ether with temperature were measured by a static method. Binary VLE data were fitted to the Redlich-Kister, Wilson, NRTL, and UNIQUAC models employing the maximum likelihood procedure. Binary parameters of individual excess molar Gibbs energy models were obtained assuming the ideal behavior of the vapor phase. A good agreement between the experimental and correlated data was found. A comparison of the fit goodness of the selected G E models is presented. The experimental data of the single component equilibrium measurements were correlated by the Antoine equation applying the least-squares method.
