The viscosities(η), speed of sounds (U) and densities(ρ) for the two fold mix of benzyl benzoate and mole fractions of alkanols have been measured with the standard techniques from [T = 303.15 to 313.15K] with 5K interval. Several thermoacoustic properties such as isentropic compressibility (s), molar volume (Vm), surface tension (γ), specific acoustical impedance (Z) and their excess quantities were deliberated from these measured data. The excess quantities have been fitted to the Redlich–Kister type polynomial equation to assess the ideality behaviour of the twofold mix. Finally, Lennard Jones potential repulsive term exponent(n), available volume(Va) and relative associations(RA) are also deliberated for the twofold mix to study the various transport and structural assets present in this benzoate mix
