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

Abstract

The current article presents the experimental density ( ρ ) and viscosity ( η ) 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 ( ∆η ) 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- π interaction, and molecules fitting in studied unlike molecules had been determined. Further, the influence of temperature on ρ, η, V E and ∆η were also reported. .
