Densities and excess molar volumes, VE, of heptane-1-chloropropane, heptane- 1-chlorobutane, heptane-1-chloropentane, and heptane-1-chlorohexane systems are reported at 298.15 K and atmospheric pressure over the whole composition range. Value of VE was found to be slightly negative at lower mole fractions and slightly positive at higher mole fractions in case of the heptane-1-chlorohexane system. For all the other systems, VE was positive. The VE results were correlated using the fourth-order Redlich-Kister equation, the maximum likelihood procedure being applied for evaluating the adjustable parameters.
