Thermodynamic, transport and spectral studies (FTIR) for some binary liquid mixtures of morpholine with isopropyl acetate, N-methylformamide and 2-propanol at various temperatures

Abstract

ABSTRACT Densities, speeds of sound and viscosities of binary mixtures of morpholine with isopropylacetate, N-methylformamide and 2-propanol including those of pure liquids, over the entire composition range were measured at various temperatures (303.15, 308.15 and 313.15) K and 0.1MPa. Using the experimental data, the excess volume, excess isentropic compressibility, deviation in viscosity, excess partial properties of the components at infinite dilution were calculated. Finally, the Prigogine-Flory-Patterson (PFP) Theory is applied to identify the most predominant molecular interaction. Jouyban Acree model was used to correlate the experimental values of density, speed of sound and viscosity. Further binary mixing and FT-IR spectra were studied at equimolar concentration. From these results, the nature of interaction has been discussed in terms of intermolecular interaction between the mixing components
