Densities, Ultrasonic Velocities, Viscosities, and FT-IR Spectra of Binary Mixtures of Morpholine in Isobutyl Acetate, Formamide, and 2-Butanol

The densities, ultrasonic velocities and viscosities of binary mixtures of morpholine along isobutyl acetate, formamide, and 2-butanol have gone determined at various temperatures over the entire composition range. From the observation data the values of deviation viscosity, excess isentropic compressibility’s ( κ ₛE ), and excess thermodynamic properties of the mixture were measured at an absolute dilution. Finally, the theory of Prigogine–Flory–Patterson (PFP) is correlated to recognize most prevalent interactions among the molecules. The Jouyban Acree version was used-up to coordinate the laboratory values of density (ρ), speed of sound, and viscosity (η). Further binary mixing and FT-IR spectra were studied at equimolar concentration have been estimated. The observations were analyzed and explained in terms of molecular package and type of interactions through the formation of hydrogen bonding.
