Densities, speeds of sound, and viscosities of binary mixtures of methyl benzoate (MB) with ethanol, 1-propanol, and 1-butanol were measured at temperature ranging from T = 293.2 to 313.2 K and refractive indices were determined at T = 303.2 K. Excess molar volumes, V E , isentropic compressibility deviations ∆κ s and viscosity deviations, Δη, were obtained and fitted with the Redlich-Kister equation with satisfactory results. Based on the measured and derived physicochemical properties, the influence of the alkyl chain length of the alcohol on the molecular interactions of the studied mixtures was explored. The results show that both hydrogen bond interaction between carbonyl group of MB and hydroxyl group of alcohol and the packing efficiency, such as accommodation of alcohol in the interstice of MB, play an important role in the microstructure of the mixtures, which leads to the disruption of alcohol with the addition of MB. Moreover, by comparing V E , ∆κ s and Δη values of MB (1) + alcohol (2) systems at T = 303.2 K, it is found that the strength of hydrogen bond interaction and the packing efficiency significantly weakens with increasing alkyl chain length of alcohol in going from ethanol to 1-butanol, resulting in the V E values of the studied systems gradually changing from a negative deviation to an S shape, the ∆κ s and Δη values have negative deviations, and the ∆n D values have positive deviations. The obtained results will provide thermodynamic guidance for the industrial purification of methyl benzoate.

Density (ρ), and dielectric permittivity (ε) of the binary mixture of ethylene glycol + 1- propanol have been determined as a function of mole fraction of ethylene glycol at T = (298, 308 and 313)K. These measurements have been employed to compute thermodynamic properties like molar volume (V), and molar polarization (P) of the liquid mixtures. Excess properties such as VE, εE and PE for the binary mixture have also been calculated at different temperatures. In order to calculate the standard deviations of the excess properties, Redlich – Kister polynomial equation was used. The negative and positive values of the excess properties predicted the type and strength of molecular interactions between the components in the binary mixture.The excess molar volume for the mixture at all temperatures is found to be negative. The εE values for ethylene glycol + 1-propanol has been found to be negative at 298K and but positive values are obtained at 308 and 313K. The divergent magnitudes of εE values at different temperatures have been attributed to different strengths of hydrogen bond interactions as well as alignments of net dipoles.

“…Additionally, physical properties of binary mixtures are essential when heat transfer and mass transfer phenomena involved in industrial processes 2 . A considerable amount of research studying the properties of binary solvent mixtures has been published in the recent decade [3][4][5][6][7][8] . Hydrogen bond formation, dipole-dipole, and charge transfer interactions have been suggested as the mechanisms of interactions between of solvents [9][10][11] .…”

To understand the nature of molecular aggregation between two solvents, excess properties (e.g. excess molar volume (V ), excess Gibb's free energy of activation viscous flow (∆G* E ) and viscosity deviation of binary mixtures) are therefore needed. Thus, in the current study, the refractive index (nD), viscosity (η), and density (ρ) of binary mixtures were measured for tetrahydrofurfuryl alcohol (THFA) with ethanol, 2-propanol and 2-butanol at 298.15K. Moreover and based on experimentally obtained results, the V , the refractive index deviation (∆nD), excess molar viscosity (η E ) and ∆G* E were calculated. To correct and fit the experimental V , η
