Intermolecular Interactions in Ethyl Methanoate and C4-C7 1-Alkanol Mixtures: Experimental and Modeling

Abstract

This study reports experimental measurements of the density and viscosity of mixtures containing ethyl methanoate and 1-alkanols (from 1-butanol to 1-heptanol) at 0.1 MPa and temperatures ranging from 293.15 K to 323.15 K. The derived properties (excess molar volume and viscosity deviation) were well correlated using the Redlich-Kister model. Additionally, the PC-SAFT equation of state provided an accurate representation of the experimental density data, and the highest quantitative agreement for the excess molar volume was obtained with fitted approach of PC-SAFT. In this work, it was found that the attractive intermolecular forces between different molecules are weaker than those between molecules of the same type.
