Study of volumetric and electromagnetic properties of binary and ternary mixtures of {2-Propanol (1) + 1, 3-Diaminopropane (2) + 2, 5- Dimethoxytetrahydrofuran (3)} at (298.15- 328.15) K at 81.5 kPa-Prediction with geometrical models

The densities, ρ and refractive index, nD of mixtures consisting of 2-Propanol, 1, 3-Diaminopropane, and 2, 5-Dimethoxytetrahydrofuran have been measured at different temperatures. VEm, Em,i,  ΔnD , αE and (ǝHEm / ǝP )T,x for binary and VEm and ΔnD for ternary mixtures were derived. VEm and ΔnD for binary mixtures were correlated with the Redlich‒Kister equation and for ternary mixtures were correlated with several equations. Prediction geometrical solution models were used to predict VEm, ΔnD of ternary mixtures and standard deviation for their fitting was reported. Positive deviation from ideal state were recorded for VEm in mixture of 1, 3-Diaminopropane + 2, 5-Dimethoxytetrahydrofuran and 2-Propanol + 2, 5-Dimethoxytetra-hydrofuran mixtures. However in mixture of 2-Propanol and 1, 3-Diaminopropane negative deviation in the high composition of 1, 3-Diaminopropane varies to positive in the dominated mole fraction of alcohol which was analyzed to interpret the molecular interactions.
