In this work, the refractive indices (nD) of binary mixture of diisopropylamine (DIPA) and tributylamine(TBA) (as sec- and tert-amines) with alkanol (methanol, ethanol, 1-propanol, 2-propanol) were measuredfrom 298.15 K to 318.15 K. The sec- and tert-amines were selected to study the effect of branching atN-atom of amine on intermolecular interactions with alkanols having different chain length. It wasfound that the TBA interacts strongly with alkanol in comparison to DIPA due to steric hindranceoffered by isopropyl group at N-atom. Various mixing rules were applied to evaluate the refractiveindex compared well with the experimental refractive indices data for the present binary mixtures.The experimental refractive indices was also fitted to Redlich-Kister polynomial.
