Effect of temperature and chain length on the viscosity and surface tension of binary systems of N,N-dimethylformamide with 1-octanol, 1-nonanol and 1-decanol

•Effect of temperature and chain length on η and σ of DMF+1-alkanol binary systems.•Viscosity and surface tension were obtained.•Δη, Δσ and G∗E were calculated using the experimental data.•Hσ and Sσ were determined using the surface tension data.•Semi-empirical relations were used to estimate the viscosity of liquid mixtures. Viscosity and surface tension of binary systems of N,N-dimethylformamide DMF with higher 1-alkanols (C8–C10) were measured at atmospheric pressure and four different temperatures over the entire range of mole fraction. The experimental measurements were used to calculate the deviations in viscosity and surface tension. Furthermore, the excess Gibbs free energy of activation, surface enthalpy and surface entropy of the (DMF+1-alkanols) binary mixtures were determined. In addition, the deviation and excess properties were fitted to the method of Redlich–Kister (R–K) polynomial. Viscosity data of the binary systems were correlated with three different expressions (Grunberg and Nissan, the three-body, and four-body McAllister). The effects of the chain length of the higher 1-alkanols and temperature were investigated.
