Refractive indices (nD), viscosities (η) and densities (r) were deliberated for the binary mixtures created by dipropyl amine with 1-octanol, 1-heptanol, 1-hexanol, 1-pentanol and tert-pentyl alcohol at temperature 298.15 K over the perfect installation extent. The function of Redlich-Kister were used to calculate and renovated of the refractive index deviations (ΔnD), viscosity deviations (ηE), excess molar Gibbs free energy (ΔG*E) and excess molar volumes(VmE). The standard errors and coefficients were respected by this function. The values of ΔnD, ηE, VmE and ΔG*E were plotted against mole fraction of dipropyl amine. In all cases the obtained ηE, ΔG*E, VmE and ΔnD values were negative at 298.15K. Effect of carbon atoms number in the chain of alcohol and hydroxyl groups' position on molecular interactions in these mixtures has also been discussed.
