Abstract

In this study, we aimed to investigate the refractive indices at a temperature of 293.15 K and the density data at T = 283.15, 293.15, 303.15 and 313.15 for binary mixtures of 3-diethlyaminopropylamine 3-DEPA with 2-propanol, or monoethyleneglycol as a function of composition under atmospheric pressure. For this study we used experimental values of density to assess the volumetric properties such as excess and excess partial molar volumes of components at infinite dilution. The Redlich-Kister equation was used to fit and estimate standard deviations for excess molar volume results. Notably, our results revealed that the binary mixtures investigated displayed negative deviations from the ideal behavior due to dipole-dipole interactions and hydrogen bonds. Furthermore, the measurements of refractive index and the variations in refractive index were also determined.
