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

Excess molar volume, excess isentropic compressibility, deviation in viscosity and excess Gibbs free energy for activation of viscous flow for binary mixtures of allyl alcohol (AA) with 2-methyl-2-butanol (2M2B), 2-methyl-1-butanol (2M1B) and 3-methyl-2-butanol (3M1B) components in different compositions were determined from the measured values of densities (ρ), viscosities (η) and speeds of sound (u) of pure components and their mixtures at various temperatures ranging from 303.15 K to 313.15 K. The excess properties have been discussed in terms of disruption of H-bonding and dipole–dipole interaction between the components of the mixtures. The Jouyban–Acree model results are discussed in terms of mean relative deviation (MRD) and individual relative deviation (IRD) between calculated and experimental parameters as an accuracy criterion and obtained a good agreement. The thermodynamic functions of activation of viscous flow have been estimated and tested. FTIR studies further confirm the experimental findings.
