Abstract
Abstract The molecular interactions have been studied in the binary mixtures of 1-tert-butoxy-2-propanol (CH3)3COCH2CH(OH)CH3 with four structurally different alcohols, viz., 1-propanol CH3(CH2)2OH, 2-propanol (CH3)2CHOH, 1-butanol CH3(CH2)3OH and 2-butanol CH3CH2CH(OH)CH3, through the behavior of measured densities, ρ, speeds of sound, u at 293.15, 298.15, 303.15, 308.15 and 313.15 K and viscosities, η at 298.15, 303.15 and 308.15 K. The experimental data were used to calculate the excess molar volumes, VmE, excess molar isentropic compressibilities, KS,mE and deviations in speed of sound, uD. The apparent and partial molar properties and their deviations at infinite dilution were also calculated. Viscosity data were used to compute deviations in viscosity, ∆η and excess Gibbs energy of activation of viscous flow, ΔG⁎ E. Furthermore, the change in free energy, ΔG, change in enthalpy, ΔH and change in entropy, ΔS of activation of viscous flow have also been calculated. A Redlich–Kister type equation was applied to fit the excess molar volumes and deviations in isentropic compressibility, speeds of sound and viscosities data. The FT-IR and 1H NMR studies of all mixtures were also reported.
