Physicochemical properties, theoretical modelling and molecular interaction analysis in ternary liquid mixtures containing 1-propanol, 1,3-diaminopropane and ethyl acetate at temperature 298.15–318.15 K

•Measured ρ, η, u and nD of 1-propanol (1) + 1,3-diaminopropane (2) + ethyl acetate (3).•Evaluated VmE, Δη, Δu, ksE, VfE, LfE, VaE and ΔnD from the measured properties.•VmE data analyzed in terms of Singh, Nagata and Cibulka equations.•u data analyzed by Schaaff’s collision factor theory (CFT) and Jacobson’s free length theory (JFLT).•Analyzed data were interpreted in terms of molecular interaction.
