Thermophysical study of the n-hexane or n-heptane with 1-chloropropane systems

► VE, κSE, and ΔnD at (283.15-313.15) K were obtained for (hexane or heptane) + 1-chloropropane. ► Isothermal vapour liquid equilibrium at 298.15 K has been also determined. ► Excess Gibbs functions were calculated from the experimental data. ► Discussion is focused on the alkane effect over dipole-dipole interactions. ► Results are compared with previous for alkane + chloroalkane or cyclic ether + chloropropane.
