Thermo physical studies on binary mixtures of furfural + n-butyl acetate or isobutyl acetate or tert-butyl acetate at T = (298.15, 303.15, 308.15) K
In the present communication, we have reported the experimental measurements on the () speed of sound (u) and dynamic viscosity (η) for furfural (FA), butyl acetate (BA), isobutyl acetate (IBA) and tert-butyl acetate (TBA) and their binary mixtures taking furfural as common component at T = (298.15, 303.15, 308.15) K over the entire composition range. The experimental data for density, speed of sound and dynamic viscosity were further utilised to compute excess molar volume (V_m^E), excess molar isentropic compression (K_(S,m)^E), excess speed of sound (u^E), dynamic viscosity deviation (Δη), excess Gibb’s free energy of activation for viscous flow (ΔG^(*E)) and partial molar volume (). Furthermore, these calculated properties have been correlated using a Redlich–Kister type polynomial equation through the method of least squares to estimate the binary coefficients.
