Vapor-Liquid Equilibria of Binary and Ternary Mixtures of Benzene,Cyclohexane,and Chlorobenzene at 40.0 kPa and 101.3 kPa

摘要

Vapor-liquidequilibrium data were measured at isobaric conditions for the binary mixtures ofbenzen +cyclohexane, benzene + chlorobenzene, and cyclohexane + chlorobenzene, and one ternary mixture ( benzene + cyclohexane + chlorobenzene. The measurements were made in an equilibrium still wit" circulation of both theyapor and liquid phases. Thermodynamic consistency for the three binary mixture was tested using the area and point-to-point test. The second virial coefficients obtained by the Tsonopoulc method were used to calculate the vapor-phase fugacity coefficients. The parameters of th~ Wilsor UNIQUAC, and NRTL equations were obtained by fitting to the binary and ternary data.
