Density, viscosity, and refractive index data for the ternary system ethyl butyrate + diethyl succinate + isobutanol and binary system ethyl butyrate + diethyl succinate have been measured in the temperature range 288.15–323.15 K, with temperature step of 5 K, and at atmospheric pressure. The measurements were performed on an Anton Paar DMA 5000 digital vibrating tube densimeter, Anton Paar SVM 3000 digital viscometer, and Anton Paar RXA 156 refractometer. Based on the corresponding binary data, as well as ternary data, presented in this work, excess molar volumes (VE), viscosity deviations (Δη), and refractive index deviations (ΔnD) were determined and fitted by the Redlich–Kister and Nagata–Tamura polynomial equations. The influence of mixture composition on values of excess molar volume, deviation functions, and the molecular interactions present in the mixtures was further discussed.
