Isothermal vapour-liquid equilibrium data for the binary propan-2-one pluschloroalkanes mixtures at temperatures from 298.15 K to 313.15 K

Isothermal vapour-liquid equilibrium data are reported for binary mixtures of propan-2-one with 1,1,2,2-tetrachloroethane (I) and 1,4-dichlorobutane ( II) within the 298.15-313.15 K temperature range. Total vapour pressures we re measured by a static method, the mixtures beeing prepared by weight and degased directly into the working cell. The experimental data were correlat ed by Barker's method and different expressions for excess Gibbs energy wer e tested. The results indicate negative deviation from ideality for mixture (I), while mixture (II) behaves almost ideally, with slightly positive dev iations. (C) 1999 Elsevier Science B.V.
