Abstract: Experimental densities (ρ), viscosities (η), refractive indices (n), and sound velocities (u) were measured at 298.15 K and atmospheric pressure for binary liquid mixtures of isopropyl benzene (cumene) with ethylbenzene, toluene, mesitylene, n-propylbenzene, tert-butylbenzene, and biphenyl. Based on these experimental results, various thermodynamic excess functions and deviation properties were subsequently evaluated. Physical properties such as density, viscosity, speed of sound, and refractive index play a crucial role in determining the excess thermodynamic properties of chemical mixtures. These properties provide valuable insight into molecular interactions and help predict the behaviour of complex chemical systems. However, comprehensive experimental data for these parameters are not always available for all mixtures, which limit the accuracy of thermodynamic modelling and analysis. The study provides new sets of experimental data, and the results indicate that the intermolecular interactions in the binary systems of isopropyl benzene (cumene) with the investigated aromatic hydrocarbons (ethylbenzene, toluene, mesitylene, n-propylbenzene, tert-butylbenzene, and biphenyl) are relatively weak.
