Abstract: Densities (ρ) and dynamic viscosities (η) for three binary mixtures of n-decane with 1-pentanol, 1-hexanol and 1-heptanol are presented at temperatures from 293.15 to 363.15 K and atmospheric pressure over the entire composition range. The density and viscosity are measured using a vibrating tube densimeter and a cylindrical Couette type rotating viscometer, respectively. Excess molar volumes (VE), viscosity deviations (Δη) and excess Gibbs energy of activation of viscous flow (ΔG*E)) are calculated from the experimentalmeasurements. Intermolecular and structural interactions are indicated by the sign and magnitude of these properties. Partial molar volumes and infinity dilution molar partial volumes are also calculated for each binary system. These results are correlated using Redlich-Kister type equations.
