Isothermal vapour-liquid equilibria for ternary and quaternary systems of butyl chlorides with nheptane, toluene and methylcyclohexane at 323.15 K

Isothermal P, x and y data were measured in ternary and quaternary systems containing one of butyl chlorides (1-chlorobutane, 2-chlorobutane, 2-chloro-2-methylpropane) with n-heptane, toluene and methylcyclohexane. The data were smoothed by means of the maximum likelihood method using 3-suffix Margules, Van Laar, Wilson, NRTL (α = 1) and UNIQUAC equations. The DISQUAC model was applied to the prediction of data for ternary and quaternary systems.
