Volumetric and viscometric study with FT-IR analysis of binary systems with diethyl succinate and alcohols

• Densities of three binary mixtures with diethyl succinate and alcohols are measured.
• Viscosities of three binary mixtures with diethyl succinate and alcohols are given.
• Excess and deviation functions have been calculated.
• Fourier transform infrared (FT-IR) spectroscopy analysis has been conducted.
• Molecular interactions present in the mixture have been analyzed.

Density, viscosity and refractive index of binary mixtures consisting of diethyl succinate + 1-propanol, or +1-butanol, or +1-hexanol have been measured at atmospheric pressure and over the temperature range from 288.15 K to 323.15 K. Excess and deviation functions have been calculated from these data and fitted to the Redlich-Kister equation. The values of excess molar volume and deviation functions, with Fourier transform infrared (FT-IR) spectroscopy, were further used in the analysis of molecular interactions present in the mixture as well as the temperature influence on them.
