The densities of the following: (pentane + 1-chloropropane, or 1-chlorobutane, or 1-chloropentane, or 1-chlorohexane), (hexane + 1-chloropropane, or 1-chlorobutane, or 1-chloropentane, or 1-chlorohexane), (heptane + 1-chloropropane, or 1-chlorobutane, or 1-chloropentane, or 1-chlorohexane), (octane + 1-chloropropane, or 1-chlorobutane, or 1-chloropentane, or 1-chlorohexane), were measured at T = 298.15 K by means of a vibrating-tube desimeter. The excess molar volumes VEm calculated from the density data, are negative for (pentane + 1-chloropentane, or 1-chlorohexane) and (hexane + 1-chlorohexane) over the entire range of composition. (Pentane + 1-chlorobutane), (hexane + 1-chloropentane) and (heptane + 1-chlorohexane) exhibit an S-shaped VEm dependence. For all the other systems, VEm is positive. The VEm results were correlated using the fourth-order Redlich-Kister equation, with the maximum likelihood principle being applied for determining the adjustable parameters.
