Thermodynamic properties of binary liquid mixtures of isoamyl alcohol with heterocyclic compounds at varying temperatures

The current article presents the experimental density (rho) and viscosity (eta) values were re ported as a function of mole fraction for the binary liquid mixtures of isoamyl alcohol (IAA) + heterocyclic components (NCHC) namely; piperidine, pyrrole, pyridine, morpholine, and quinoline at the temperatures T = (293.15 to 313.15) K with 10 K intervals under atmospheric pressure (0.1 MPa). Based on experimental data, the excess molar volume (V-E), viscosity deviation (Delta eta) was calculated. These values were correlated to the Redlich-Kister (R-K) model at measured temperatures. The obtained excess molar volume was negative deviations and deviation in viscosity was positive at the above said temperatures. From these results, the new H-bond, OH-pi interaction, and molecules fitting in studied unlike molecules had been determined. Further, the influence of temperature on rho, eta, V-E and Delta eta were also reported.
