Study on the molecular interactions of binary mixtures of allyl alcohol and amino-alcohol solvents through thermodynamic properties and FT-IR spectra and correlation with the Jouyban–Acree model

Abstract

ABSTRACT Densities (ρ), speeds of sound (u), and viscosities (η) for three binary mixtures of allyl alcohol with 3-amino-propan-1-ol, 2-amino-2-methyl-propan-1-ol (aminomethyl propanol), and 1-amino propan-2-ol (isopropanol amine) were calculated at temperatures ranging from 303.15 to 313.15K and at atmospheric pressure over the entire composition range. Experimental measurements were used to calculate the excess molar volume, excess isentropic compressibility, deviation in viscosity, and excess Gibbs free energy of the activation of viscous flow. Partial molar properties and partialmolar properties at infinite dilution are also calculated. The Prigogine–Flory–Patterson (PFP) theory is applied to identify the predominant molecular interaction. The results of the Jouyban–Acree model are discussed in terms of the mean relative deviation (MRDs) and individual relative deviation (IRD) between the calculated and experimental parameters as an accuracy criterion. FTIR studies have also been added to confirm the experimental findings of the investigated mixtures.
