Densities (rho) viscosities (eta) and ultrasound velocities(u) for binary mixtures of isopropylethanoate and non-polar hydrocarbon solvents viz cyclohexane benzene 1 4-dimethylbenzene and 1 3 5-trimethylbenzene have been measured at 308 15 K Adiabatic compressibilities(beta(ad)) available volume(V(a)) and acoustical impedance(Z) for the binary mixtures are evaluated from the ultrasound velocity and density data Deviations in viscosity (Delta eta) in ultrasound velocity (Delta u) and in compressibility (Delta beta(ad)) from their additive values for all the systems studied are evaluated from the experimental values for the mixtures and their components at experimental temperature Delta eta and Delta u values are negative and Delta beta(ad) are positive for cyclohexane + isopropylethanoate binary mixture Several models for mixture viscosity are analysed The strength of interactions are discussed in terms of Grunberg and Nissan interaction parameter (d) Hind-McLaughlin-Ubbelohde viscosity equation is
