Abstract
The density (Ï) and viscosity (η) data were measured on the binary system of dipropylene glycol (DPG) + 1,2-ethanediamine (EDA) with the different mole fractions at (293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K under atmospheric pressure. On the basis of the experimental Ï and η data, the excess molar volumes (VmE) and dynamic viscosity deviations (Îν) were calculated. Meanwhile, the Redlich-Kister type function was employed to calculate the coefficients and evaluate the standard deviation between the experimental and calculated data by using VmE and Îν values. After that, the intermolecular interactions between EDA and DPG was discussed according to FTIR and UV-vis spectral results.
