The excess molar volume (VmE), deviation in dynamic viscosity (Δη), excess Gibb's energy of activation were calculated from the measured density (ρ) and dynamic viscosity (η) for tributylamine (TBA) with alkanol (C1-C3) at T = (298.15–323.15) K and at pressure of 0.1 MPa. The partial, excess partial and apparent molar volumes were derived from VmE values. The Δη were described by Singh model as well as by Bloomfield and Dewan model. It was found that depolymerisation power of alkanol depends on the unlike interactions between TBA and alkanol. The thermodynamic parameters of activation for present binary mixtures were also calculated. The η values were further correlated using models/correlations with zero to four adjustable interactional parameters like Kendall-Monroe, Bingham, Arrhenius, Kendall, Frenkel, Grunberg-Nissan, Tamura-Kurata, Hind-McLaughlin-Ubbelohde, Katti-Chaudhari, McAllister's, Heric, Iulian, Krishnan and Laddha correlations. The prediction capabilities of these correlations/models were expressed in terms of standard deviation.
