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
