Vapour pressures of (tetrachloromethane + α,ω-dichloroalkane)

Total-pressure vapour-liquid equilibrium measurements, on { xCCl 4 + (1 − x)Cl(CH 2) m Cl} ( m = 1 to 4), at 303.15 K, by a static method were made. Composition of vapour, along with the activity coefficients and excess molar Gibbs free energies G m E were calculated by Barker's method. G m E(...

Description
Summary:Total-pressure vapour-liquid equilibrium measurements, on { xCCl 4 + (1 − x)Cl(CH 2) m Cl} ( m = 1 to 4), at 303.15 K, by a static method were made. Composition of vapour, along with the activity coefficients and excess molar Gibbs free energies G m E were calculated by Barker's method. G m E( x = 0.5) remains more or less constant for almost all the mixtures because of a compensating excess molar entropy decreasing as the length of the dichloroalkane increases.
