Theoretical Modeling and Experimental Study of Ester-Alcohol Interactions: Methyl Heptanoate and 1-Alkanols

This manuscript investigates different properties of binary mixtures composed of methyl heptanoate and a series of 1-alkanols (from 1-propanol to 1-hexanol) at atmospheric pressure (0.1 MPa) and temperatures ranging from 293.15 K to 323.15 K. Our experimental data shows that weak intermolecular interactions between the methyl heptanoate and 1-alkanol. Additionally, we employed the PC-SAFT equation of state to accurately predict the density of the mixtures. On the other hand, two viscosity correlations (Redlich–Kister and Belda) were also tested, both of which provided a good fit to the experimental viscosity data.
