In the frame of a project dealing with phase equilibria in ketones + chloroalkanes, isothermal vapour-liquid equilibrium P-x-y data are reported for binary mixtures containing pentan-3-one with 1,2-dichloroethane (from 323.15 to 353.15 K), 1,3-dichloropropane (from 343.15 to 373.15 K), 1,4-dichlorobutane (from 343.15 to 373.15 K), trichloromethane (from 313.15 to 343.15 K), 1,1,1-trichloroethane (from 323.15 to 353.15 K), and 1,1,2,2-tetrachloroethane (from 343.15 to 373.15 K). In order to complement the data on VLE, and to investigate the influence of molecular structure of these chloroalkanes in their mixtures with pentan-3-one, molar excess volume, VE, obtained from the density measurements at 298.15 K and atmospheric pressure, over the whole composition range are presented. The VLE and VE experimental data are correlated by means of the Redlich-Kister equation using the maximum likelihood procedure.
