N2 - This study presents new experimental measurements of density and viscosity for binary mixtures of propanal with 1-alkanols (from 1-propanol to 1-heptanol) at 0.1 MPa over the temperature range of 293.15 K–323.15 K. Theoretical excess molar volume values, calculated using the Peng–Robinson cubic equation of state with van der Waals mixing rules and the Redlich–Kister correlation, show qualitative agreement with the experimental data reported. The results indicate strong attractive interactions between propanal and the alcohols, leading to negative excess molar volumes and positive viscosity deviations.
